My original headlights lasted almost 10 years now they die about every 6 weeks right side original die the 1 month later left side died now both have died 2 to 3 times. Is something wrong with the light system any one else have this problem.
Are you installing aftermarket HID? Did you touch the bulb with your finger tip? Wear glove and try not to touch the bulb when you install it. Which brand did you use. Just wondering.
Sylvania bulbs going to try different brand replacing bulbs is getting old may go to Toyota and get OEM bulbs original last long time
Isn't there a known issue with corrosion of the headlight wiring terminals in the bulb connectors? OP, check for corrosion in the connectors. That can cause poor conduction of the current to the bulbs and cause the premature failure you are having.
Same problem clean connectors and apply dielectric grease after clean .also take duct seal apply around connector to seal out moisture.also Sylvania are junk blubs OEM are Philips.syvania warranty blub one year . will send you free sets have received all have fail longest last nine months 9 days. Switch to Philips all well
