Stereo & Electronics - Replacing turn signals with LED array

I'm thinking of replacing the bulbs in my daytime running lights/turn signals with an array of high-output LEDs, but I need to know a general figure on the amount of mcd output by our 2 different bulbs in each lens when constrained to about a +-15 deg output width. I'd probably replace each one with ~12 40k MCD white LEDs but I dont know if that would be bright enough.

If anyone knows fill me in :D

40K people will definetly see that. Just remember LED's are real directional. They don't flood well. But I think it will work.

yeah which is why I would use such a large array, I would curve it around to fit the profile of the lens. Plus the lens itself should diffract the light some.

Cool idea! Do it do it! Post pics too! ;)
