This blue LED halogen replacement bulb is smaller than most so we have found it fits in most lights that have 10W halogen G4 bulbs where the bulb is inserted from behind (back pin). This includes many reading lights and some overhead "puck-style" lights. It puts out bright blue light for adding "bling" to your boat! The pins are 1/2" and can be trimmed if needed, to allow it to fit inside many different lights.
Operates from 10-30 volts DC, includes filter for electromagnetic interference and voltage regulated to protect from voltage spikes.
OD - 1.18"
Pin spacing is .16" (same as a G4 bulb pictured)
Pins may be trimmed to allow fit in smaller lights.
