I'm purposely posting here to ask if any other BMW MC has this wedge base W5W/T10 halogen bulb in the HL/parking light area of the bike? My 2012 G650GS uses it for the parking light(why a parking light on a bike?)which has it's own reflector. I'ts beside the HL reflector in the same unit & side by side. It puts out a paltry 64 lumens I'm searching for a way to add some conspicuity(besides my aux lights) & maybe some down the road light too.
There are super bright T10 style LED bulbs for sale with 700 lumens,(as much as some small aux lights) drawing 12 watts/1 amp and measure 30mm,barely longer than my halogen oem bulb which is ~23-24mm.The chips are on the side of a blade so should get reflected OK. Some have chips on the tip and only seen at end of tip & not reflected well.
Have you got a MC that uses the same oem bulb? Have you tried the led's I mention?
