I have a light bar with 6 halogen fixtures, 2 of which currently work. It appears to be a combination of broken fixtures and blown bulbs. Rather than replace a bunch of halogen bulbs, I'd like to switch to LEDs while I'm repairing fixtures and drastically decrease the current draw. Has anyone found replacement LED bulbs that are simply plug and play? If not, does anyone make new housings? I suspect I'll probably have to buy new fixtures or a whole new bar.
