 LED Headlights: Turning on the fogs turns on the high beams, too!, New behavior, fogs worked normally until LED headlights installed. |

I love my brand new GE Nighthawks. There is no way I could go back to regular headlights. I had a set of sealed beam Hellas.
Last night I turned on the fog lights for the first time and the high beams came on. When I looked at the front of the car, all three were on: the regular lights, high beams AND the fog lights. Any fix for this? I would like to have the fog lights and the low beams on at the same time without the high beams. Edit: up until I installed the LED headlights, turning on the fog lights did NOT turn on the high beams. And turning on the high beams turned OFF the fog lights. In other words, normal behavior. Thanks, Paul |

Spoke/Mark/all - thanks for spending the time to get this sorted. I'm away from my new-to-me 2.0 but this is really going to help as upon initial inspection I found that the current H4 reflectors were deteriorated and I was wondering what route I should take - stay with H4's or go LED. I really wanted to go LED but not if there was going to be collateral "damage" - can't wait to get back to the midwest where the 914 is living so I can tackle this. oh - and placing an order for Spoke's LEDs and some rubber from 914 Rubber...great resource here!!

If you dont have fog light there are no known malfunctions. LEDS can have some strange affects on related systems. Was told of a user installed LED backup bulb in a Chevy truck. Caused a trans error light. They pulled the teams and went thru it and no internal problems were found. Many newer cars need a canbus to avoid erroneous errors from being generated. Bruce |
