I was just changing over my front H7 headlight bulbs yesterday to Xenon effect bulbs...as these defo do make the light output more clear and white!!
Anyway, while at it, I decided to change the sidelight (501) type bulbs for led ones...see pic...
Now they do look good, but I noticed when I switched off car and lights and locked her up, these LED type bulbs were still on, not on full power, but dimmed.
I then looked in car and the dash read out where it tells you if doors are open etc, was showing the front bulbs.
Has anyone ever replaced their sidelight bulbs with these types of leds, and if so, had the same issue?
