Has anyone tried changing all the exterior bulbs (not headlights.) to LED's?
You mean Amperage requirement. 12V on a LED would blow it. You either have 3-4 in series or a resister in series. It blinks fast because there is less draw on the system. This happens to most cars and yes a Cap can fix this.I've done all the bulbs in the rear. The one thing that you have to watch out for is due to the low voltage requirement of the LED's... the FJ thinks that a turn signal bulb is out thus causing the signal to rapidly flash when it is on; you can counter this with a capacitor but I kind of like it.
