Put a couple of "excellent" LED running lights on the highway bars of my 09 1200L Sporty. ( Superbriteleds.com ) They look and work great but headlight is very yellow compared to the LEDs. I purchased a couple of LED H4 headlight bulbs with intent to replace the regular bulb. LEDs will not light up. Power to headlamp plug is good. LEDs work if I test them with a 12V battery. Sooooo, question is, is the headlamp relay operation dependent upon the actual load of the bulb. A regular H4 of 12V - 55 Watts would put about a 4.5 amp load back on the relay. The H4 LEDs only put about a quarter of that. Is the relay not closing when the LED is in the lampsocket? Any ideas? I'm not electrically educated enough to completely understand loads and feed back loads.
