I don't see it being worth it. Honestly if they were that much better I think they would be around A LOT more, and used in many more newer cars.

Im gonna get these, but theyre $60 a pair so Ill wait a bit. But then I can drive with just parking lights and fogs on around town, cuz the 60 led ones will be bright as heck.

thats pretty cool

I like those switch back bulbs a lot. I may steal your idea.

i think they are pretty good but not much differentiable with HIDs. these kinds of bulbs and kits have really proven to be useful at night times

I wouldn't buy from ebay with this or HIDs...how ever for LEDs i would use www.superbrightleds.com thay are way cheaper for the same thing...
