At least 50% brighter than the 60/55w halogen and 100% brighter than the original round tunsten bulb. Commonly known as the HB12, P45 or 410, this bulb is a replacement for the tungsten filament 410 bulb used widely in the 50's to early 80's. P45 indicated a diameter of 45mm for the plate which carries the bulb and fits into the back of the reflector. No re-wireing is required although a relay is recommended and increases the light output. This bulb draws approximately 8 amps.
