No Point. The resistor limits the current more than enough and LEDs can take quite a surge. As for low brightness at low voltage, who drives with the engine off? When it runs the battery should be 13.5 to 14.2V. There may be some drop to the lights and fuse board but not enough to worry. If there is a large drop then your system is probably overloaded or regulator knackered and needs looking at. -- John Email:#jrfeng#@ozemail.com.au PS: remove #'s.
