can i get ticketed for running "home made" led tail lights with factory covers?
or do they have to be approved "bulbs"

I dont think they have an approval for bulbs, as long as they work

you can use a clear lense. If you are using red coloured leds, Becare full the forward current. You dont want to hot or bright of leds. I think you can get 280 lumen red leds now. I did all my lights in my landcruiser led. You will need a PWM circuit for tail lights. Your tail lights are your trim lights and stop lights most likely. LTC 3780 is a really good IC for what you want. You would controll all your back lights with one IC. I have all the schematics if you want them. You make your own PCB from them.
Here is an ideal IC http://www.linear.com/pc/productDetail.jsp?navId=H0,C1,C1003,C1042,C1116,P1 0090

Don't forget a load balancer on the turn circuit, cuase the 'fast' flasher is cause for a roadside stop and maybe a ticket. Turn signals are supposed to do this when a bulb is out because the LED won't produce enough load to operate the flasher. I have also heard of an adjustable flasher but have yet to track one down.[cheers]
