There's probably no such thing as a 500lm rear light. You don't need that much light in the rear: rear lights are red, not white, so that power isn't spread out across the visual spectrum the way white front lights are. 50-150lm is more than enough to be seen in the daytime, let alone nighttime. Also, don't forget that human vision is non-linear in its perception of brightness; you don't need as much power at night to be seen with a red light as you do in the daytime.
Finally, compare to car lights. I'm pretty sure a standard halogen automotive headlight isn't even 1000lm, and those are for vehicles traveling over 65mph.

I'm looking for minimum 2000 Lumen LED front light with built in battery featuring at least 6000 mAh battery preferably 10,000 mAh and at least 500 Lumen rear lights that's designed for seat posts that isn't angled at 90 degree upright.
I have seen a lot of lights on Ebay but most of them have terrible battery and most of them don't even have built in battery
i would like these lights to be USB rechargable.

Exposure has exactly what the OP wants.

Several models have >2000 lumens and >10,000 mAh.

I've got the Taz1200, the younger brother to the one listed above in [MENTION=364968]trailangel[/MENTION]'s post.
Do you know how much light you are really asking for? 1200 lumens lights the road up like a car light. My 350 and 450 lumen NightRiders get used far more often in any sort of lit at all environment. My 50 lumen Hotrod back light is visible in the day, let alone at night.
That is what that setup looks like, with 1200/50:

I can't find anyone even claiming to use a 500lm red LED element (or combination of elements,) not even the Chinese knock-off lamps. I don't think there's a single-LED tail light out there rated above 150lm.

[MENTION=488078]dwolsten[/MENTION] is correct. No legitimate manufacturer produces a tail light claiming more than 300lm-- and those will often put out less light than a mfr. who makes a better housing and reflector.

I can't post links due to post count but you can Google "500 lumen rear light" and find the Australian Niteflux Red Zone 8 and the C&B Seen City Slicker 500 lumen rear .

In practical testing, the NIteflux was not as bright as the Dinotte 300R, and the Quad Red is significantly brighter than the 300R, despite being rated at just 200lm. The Niteflux is maybe a 150lm lamp.
The City Slicker calls itself "500lm" based on a raw estimated luminosity of the pair of CREE LEDs is uses. In the real world, the light is putting out ~100lm.
As I mentioned, a legitimate manufacturer will state an accurate rating, not the "maximum theoretical output of the elements under the best possible conditions."
This is why a 70lm Lezyne tail light will in practice be brighter and more visible than a "300 lumen super bright tail light!!" from eBay.
There is no such thing as a 500 lumen bicycle tail light. An incandescent brake light on a car is generally ~400lm-- and will be orders of magnitude brighter than an LED bike taillight, because it's putting out a broader spectrum. LED car tail lights suffer the same viewing angle problems as bike LEDs, offset by the fact that they run on 12V, use significantly bigger elements, and a lot more of them.

Since you doubt the previous two claims of 500lm, what about the American-made DS-500 tail light @800 lumens in day time mode ?

The DS-500 is probably the brightest taillight money could buy, if you could still buy it. It's literally just their headlight with red LED elements in it-- and CREE XM-L no less. It's utterly unusable at night, but puts out the light it claims-- which is why it needs a massive 7.4V R/C-car-size lithium battery to power it. The Niteflux is claiming the same lumens for a light with a built-in 800mah battery.
It's all moot anyway. The OP is most likely trolling us all, and I'm certainly not going to ditch 150lm for $25 in favor of +200lm for $200+.

I also am among those who receive complements (and sometimes rants) over my CygloLite HotShot Pro150.
Praises:
In front I have a L&M Taz 1200. It's as bright as I could ever need. I usually ride with it on its mid-bright setting and even that's plenty.
For those concerned with being seen from all angles, there is the Planet Bike Bottle Blinky, and the BrightSide Amber side light. I have the Bottle Blinky. It mounts beneath the water bottle cage on your downtube, and provides three flash patterns (continuous, gentle oscillation, and random strobe). It uses AAA batteries, and in the strobe mode lasts about 100 hours.
My reason for getting it is that people occasionally pull out of side streets, driveways, or 4-way stops without noticing me despite having my headlight and tail light. The side light just assures that there's something eye-catching regardless of their approach angle. It's not anywhere near as bright as my primary lights, but it is enough to get people's attention, I think.
Anyway, there's really no NEED for a headlight brighter than 900lm, tail light brighter than 150lm, and a quite moderate side-light. More than 150lm in back is getting into the range of causing driver confusion and possible accidents. In front, if you're brighter than a car, or less bright than a car but with a poorly-masked beam, you are blinding oncoming cars, and that's also unsafe.
Praises:
- A woman rolled down her window at a light and told me it's the best light she's ever seen. I told her some people complain it's too bright. She said, "Let them complain. We can see you."
- A police officer did a u-turn and pulled up along side me to ask what my lights were so he could recommend them in a bike safety course he conducts.
- Several other motorists have told me both in daylight and at night that it's the brightest tail light they've seen on a bike.
- One person passed me at night in his vehicle and shouted "f-ing light!"
- Every week someone shouts out their window as they pass me at night with the intent of startling me. I think the light is visible from so far back they have lots of opportunity to think of something clever (and unintelligible from my perspective as a rider) to shout as they pass by. It doesn't happen much in daylight, nor when I used to ride with a dimmer light.

Ha ha ha ... if you are afraid to put lights on your CF handlebar, you can buy the Cateye helmet mount and put the Cateye light on your helmet. Maybe there are other brands that have helmet mounts, but I am familiar with Cateye. ;. What happens when you crash with with a helmet mounted light, I don't know. Could be the light snags on the pavement and breaks your neck ...
Cateye now had lights that can sync. They have the Wearables-X so if you place two lights on your body/bike, they blink at the same rate. Plus some of their brake lights have accelerometers, as you brake, the light intensity changes. I think Garmin/Knog may have this feature as well.
p/s -May I know what motorcycle you are riding? (Never seen one like it before.)

i would like these lights to be USB rechargable.I bought a ThruniteTN4A flashlight and mounted it to my handlebar with a Two Fish. I run it on High--NOT Turbo--at 550 lumens, and it runs on 4 (rechargeable) AA batteries. I can say with confidence that its reach is equal to or better than that of the low beam headlight on my truck. This light is referred to as a "thrower," but it has enough spill to serve quite well for riding on roads.
I chose replaceable batteries so I can easily carry a set of spares and find replacements in a pinch if needed.
No one will ever outrun this light on a bicycle. I don't understand the need for excess.

The point I want to make is even at mid day my Hotshot 3W got compliments from drivers. the 50 Lm receives compliments too but it also receives hateful comments. There is also a huge battery run time difference between the 3w, and the 50Lm
I'll probably buy more 3W Hotshot while I can find them.

Save yourself the trouble and go with tested products

I have seen a lot of lights on Ebay but most of them have terrible battery and most of them don't even have built in battery
i would like these lights to be USB rechargable.Like many others who have responded, I run a Cygolite HotShot Pro (150 lu) tail light which holds charges well, offers many modes of lighting and is USB rechargeable on a micro usb plug. In night flash mode in the city, it is visible for at least .5 mile when half charged. In day flash mode I have been stopped by motorists in cars saying they could see me for at least a half mile. It is very bright and has a seat post connection which is angle variable.
I run Cygolite's Metro 850 (850 lu) as a headlight. Also USB rechargeable, it is visible for over 1 mile in day flash mode when fully charged. Since I ride in the city, I can only say that its triple night flash mode offers more than adequate light to see where you are going and to be seen by auto drivers. Battery life is good and time between recharges depends on use, but at least three or four hours of run time in either flashing mode described.
Continuous ON modes run the battery down faster but there are bright and not-so-bright modes to cover what you need.
BTW, I ran the first 50 lumen HotShot and a 75 lumen HotShot before upgrading to the Pro 150. My first headlight was a Metro 420 (420lu). Design problems with the 50 lumen HotShot were corrected in later models.

N+1 time
i got the lezyne 1100xl combo with rear 350lm - i was angry at the mechanic for putting the light on my handle bar because it was so small and it might have fractured my carbon fiber handlebar so i took it back and got a refund for the front light. I am happy with the rear light though just not the front one.
The front mount for the Lezyne 1100xl front light is joke and a disgrace.

I'd just add a wrap of Gaffers tape to cover the carbon ,
before adding a plastic bar mounted QR headlight clip..
maybe you need a 2nd bike for the dark half of the year.. outfitted differently
I have a bike with mudguards and pannier racks (on the fork) for keeping rain gear handy..
hub dynamo powered lights , so battery run time is a non issue..
plastic/'pleather' covered saddle , etc..
but I'm just a practical, old, guy.. bikes of metal..

I don't think i could afford those exposure lights they are the same price as a bike computer (garmin edge 1030) i also need a computer so that will be my next purchase (already bought a cheap light Surfas 1500 and I'm very happy with it as it was discounted by 30%.

So i have just received my fake Chinese 15000 Lumen light, just as well i bought a real 1500 lumen a couple of days ago in anticipation. This fake light is more like 500 to 600 lumen and it doesn't spread out the lights on the road (it's very concentrated in the middle and it is totally useless).
The mounting doesn't fit my handle bar but luckily it does fit my other bike I will keep it as it only cost me $10.00

Un cheap, high quality , is the Supernova Airstream 2..
Several brightness settings with run times from 2.5 to 7 hours.
overdriven LED get heatsinks to dissipate the heat generated in making them brighter..
