evor1 Posted April 6, 2022 Share Posted April 6, 2022 My driver side blinker blinks fast. The front driver side amber light will also not blink as brightly as the other side when locking/unlocking doors. I replaced it and also swapped the rear bulbs but issue is still there. Contacts were good and cleaned anyways. 2005 subaru legacy 2.5 Quote Link to comment Share on other sites More sharing options...
forester2002s Posted April 6, 2022 Share Posted April 6, 2022 This sounds like a grounding problem. One bad ground on a single bulb-holder can cause odd problems on other bulbs. Is there any corrosion around any of the bulb-holders? Does the metal body of each bulb-holder measure zero-Ohms to a good ground on the car-body? 1 Quote Link to comment Share on other sites More sharing options...
evor1 Posted April 6, 2022 Author Share Posted April 6, 2022 Would this issue be only on the driver front headlight connectors or could it be passenger side or rear as well? Quote Link to comment Share on other sites More sharing options...

Probably just on the driver's side, since your two problems are on that side. Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted April 7, 2022 Share Posted April 7, 2022 if you used an LED bulb, that can cause hyper flashing too. if a bulb has an internal problem.putting it on the other side of the car should cause hyperflashing there. 1 Quote Link to comment Share on other sites More sharing options...
evor1 Posted April 7, 2022 Author Share Posted April 7, 2022 its a regular bulb and i dont see any issues with the connectors. would a bad turn signal relay only affect one side? Quote Link to comment Share on other sites More sharing options...
brus brother Posted April 8, 2022 Share Posted April 8, 2022 check all grounds/connectors front and rear. as 1LT suggested move a known "good" bulb around as well. Quote Link to comment Share on other sites More sharing options...
evor1 Posted April 8, 2022 Author Share Posted April 8, 2022 (edited) would puling all of the front and rear bulbs work to diagnose? then add just the turn signals? assuming this works then i could just add each other bulb one by one until the issue returns Edited April 8, 2022 by evor1 Quote Link to comment Share on other sites More sharing options...
lmdew Posted April 8, 2022 Share Posted April 8, 2022 Sometimes the socket connectors do not have the contact force needed for a good conection. Bend them out a bit to increase the force. 1 Quote Link to comment Share on other sites More sharing options...
