Anyone else make their own lights?
I do, and I've been selling a few of them on eBay as well. 20w MR16s are my fav :-)
Here is one I'm selling now on eBay:
They all basically look the same, except the one I have on my rincon is painted a metallic red. I think I'm going to do up a blue one for my 10spd racer when I'm done with it.
yeah I'm in the process of building my own lights, but $200 for a single 20w mr16, and about $40 (giving you the benefit of the doubt) of ancilliary equipment is a hell of a rip off.
Is the light bulb changable after it goes? or have you just epoxied/siliconed it into its capsule?
To put the cost into perspective for anyone else who isnt familiar with it (these are british pounds... so just convert to dollars if your american).
£2.50 bought me 5 bulbs, 2 x 20w spot and flood, 2 x 38w spot and flood, 1 x 50w spot.
£9.99 bought me a charger to charge my battery (will take 7.5hrs to charge my higher capacity battery as opposed to 14hrs for his).
£12 bought me a 12v 7AH (not 4.5AH like the guys ebay auction is selling) lead acid battery.
£5 bought me mr16 bulb holders, solder, wires, switches, and cable clips to connect it all up.
So in total: £29.49 for all the gear needed to make 5 LIGHTS totalling 166 watts of lighting, Work on my bike.
So lower the price innit laddy! cause thats one hell of a rip off! :|
Yeah, I made my own with and played around with different bulbs until I settled with an MR-11 (20W and 12 degree angle). Well done Joecool 85. Your's has a nice clean look and is better made than mine, especially the connectors. I haven't given much tought to lights lately. I won't need them until next fall. The commuter forum has a long thread on home brew lights.
Its not a rip off. And $200 is the buy it now price, its starting at $99. And the reason for the 4.5aH NiMH pack is to save on weight. The whole thing weighs in at just over 1.5lbs battery included. A 7AH SLA weighs about 5-6lbs! It costs me about $65 to get the bulb, PVC, connectors, conduit hangers, paint, wire, battery and charger. Then it takes about 4 hours a piece to put together. I think its a good deal.
I think if its costing you $65 for the mounting gubbins, you need to find a cheaper supplier of your gear.
And if it takes 4hrs to put it together im assuming your missing an arm or something, its one bulb, one switch, and one battery. Granted some fabrication is involved but to make your housing out of some PVC pipe would take nigh on 2 mins with a hacksaw and heck even a hand drill. Paint... spray it and leave it, its a piece of pipe about 3 inches long... just how long does it take you?!
Connectors.. oh you mean crimp connectors, yeah... 2 seconds with a crimper.
If you have a buy it now at $200 it means that you value it at that. 1 20w light on a 4.5Ah battery is not worth $200 imo
btw... im not disagreeing that its a nice swish looking package there, and well presented, but people can build that system for next to nowt. your effectively charging them $150 for labour.
$65 includes everything, heck the battery/charger costs me $46 plus shipping. NiMHs aren't cheap. And keep in mind I have to order all of my parts (minus the PVC) online because there isn't anywhere to get that stuff locally here in Maine. As far as the hours go, you have to grind down all the crap on the PVC, fill the gap between the cap and the main piece, sand, do a fine fill to get any small areas you missed, sand again, prime, 4 coats of paint, drill all the holes, put in the conduit hanger then solder up all the wires for the switch and bulb connector as well as the wire connects (I do solder everything, crimp ons suck), and then silicone in the bulb. I could do one in under an hour, but it wouldn't look like what I am selling, thats for sure. These are quality lights, made to look good, work well and last.
I take pride in my work.
I was wrong on my hours to make one btw, I just did some math on how long it takes for each part of the process, its more like 2.5 hours of work (plus time to let paint dry, silicone set etc)
And I'm happy with a cheap/ghetto light on my bike, but I wouldn't sell one like that on eBay. I try to be as professional as possible
Joe, is the bulb replaceable?
Yeah, the bulbs are replaceable. I used the 20w Malibu CL9 light from Home Depot for about $11.50. Added a 12v 10ah lead-acid battery for another $25. Some switches and wiring for total cost of about $40. I already had a Battery-Tender for my motorcycle, so that does a fine job of charging up the battery. I'll stick in a 10w light for long night rides, lasts about 12 hours. For most of all the other riding, I'll use the 20w bulb for 6-hours burn time.

The bulb is replaceable, but it is siliconed in, so the best way to remove it would be to apply heat with a blow dryer, and then cut the silicone out with a utility knife.
Hey, what cells are you using to drive these? It looks like you've got 5 in series in the battery pack, and unless you've found some new voltage cell, most NiMH cells are 1.2V. So you are selling a 6V light.
Figure 3-4$ per cell, the battery pack only runs you 15-20$, plus 10$ for a dumb charger. You're getting screwed on your batteries. Check out http://batteryspace.com/index.asp?Pa...S&Category=227
I'd put the voltage that the system runs at in the ad so that people don't get confused and think they are getting a 12V light.
Also, I'd add some safety features and features to protect the battery, perhaps a fuse or two?
No matter how many coats of paint you put on, it'll still be a mediocre design that is adequate for personal use but would be inadvisable to sell.
Myself, I'm working on a homebrew light using a swtiching voltage regulator so that I can feed 12 ro so volts but step it up to provide a brighter light or leave it at battery voltage to conserve energy. That way, I can have the best of both worlds of energy conservation and bright light with only one type of bulb. However, I still wouldn't try to sell it, although I might put a schematic up on here.
Why hasn't this been moved into the "For Sale" forum, anyway? Isn't this close enought to an ad?
Battery space is where I'm getting my packs, and they have 10 NiMH C batteries in them. I wouldn't advertise it as a 12v if it was 6. Also, it wasn't in the for sale forum because it wasn't suppose to be about my eBay stuff, that was just a side thing I mentioned. I was more curious about how many others make their own lights, out of what, how they look etc.
