Looking for headlight LEDs for arduino RC robot car


I have this car on the way:
Arduino Car

I want to add headlights or similar lighting that will help the camera see in darkness. The car will be used mostly in the dark to look for problems in the crawlspace under a house. I've been having trouble googling for just the right parts.

I found this video that has some nice lights, but the parts aren't listed:
Car with headlights

It would be nice if the lighting would run on 5V so i don't have to add a battery pack.

This is the best option I've found online so far, any other options?
