I still think Dinotte tail lights are among the best daytime visible tails you can buy. The 300R or 400R are all most people need and the daytime 400R light is among the brightest money can buy (yes I know there are brighter lights out there.) For a front flasher that is daytime visible you probably don't need to spend more than ~$50. The more expensive headlights just allow you to see the road in front of you in the dark.
