Hello there, off the top of my head i'm not too sure what the exact name brand of the company is but you can find them on the rally trucks and jeeps with the light bars. However if you want to go for the bulb only there's companies like PIAA and HELLA those are big bulb comapnies. If you wan to get a whole assembly theres a company called The Lighting Firm and they make complete assemblies that look real cool and possibly programmable color change too. Check it out and let me know how it goes.
