If you buy from Jamstrait, purchase their Hyperbright Led's. Not the superbrights. John tested the Superbrights and they were not that bright. My company had tested the Hyperbrights and the Superbrights. The Hyperbrights will work but it depends on the type of lens on your taillight housings. Remember that these led bulbs are meant to be used with see through lenses. Anyone who has some money to burn try www.ledtronics.com or http://www.netdisty.net/ds/AUT1157/ They're Led bayonets would seem to work better in a reflective housing because of the led's mounted on the side of their bayonets. For a total of 24 led's. Ledtronics is in Torrance, CA. I'll take some comparison pics of the Hyperbrights, Superbrights and Incandescent bulbs in a DeLorean Taillight Housing and I'll post them sometime next week. I'll see if I can get a hold of a lightmeter as well. Mike Vin#1113
