1st - tried the STUPID replacement LED bulbs (1157 / 1156)
not even close to bright enough
2nd - tore apart a 2000-2005 Cadilac Deville tail light
bright enough (68 LED's equilivant to a 55watt bulb)
but the shape isn't very easy to mold into my housings
3rd - I order 1500 LED's and 12 LED circuit boards.
I'm going to build my own, and blind people behind me
I'll find out if buying the LED specific boards was worth the cost
