Right Headlight & Blinker Brighter Than Left - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Clipping_Path · 08-05-2018, 08:56 AM

2 weeks ago I noticed my right side lights were brighter than my left (OEM bulbs - no LED’s). Though all of the lights worked, my left turn signal then started hyperblinking a couple days later.

I changed both blinker bulbs. Cleaned the sockets. Still hyperblink. I had a new flasher relay on hand – replaced it. No change.

I did have some body work done a month ago where they removed my front bumper; maybe a ground is loose or dirty? I didn’t notice anything wrong directly after receiving the car from the shop.

sounds like your low on blinker fluid

I suggest you check your car's rear bulbs to make sure they are working properly. Back in the day, a turn signal could hyper blink if either the front or rear bulb was bad.

If the car were low on blinker fluid, it would throw a code and a flashing light would appear on the dash display.

I'd check the wiring, sounds like the ground somewhere on the less bright side wasn't too good.

Also remember to check the rear lights, that requires removal of the trim panel in the trunk and is super easy to do

The issue went on for a week with my OEM taillights. I had Valenti's on order; fiinally installed those and...still hyperblinks.

Where is the grounding wire in the front?

I think we all clicked this topic to make this joke.

Valentis will hyperblink if you don't have a relay that's designed to work with LEDs...

I'd have to go look at a wiring diagram to answer your question, and I'm not going to go do that for you.

I don't have LED's. All OEM front bulbs - was hyperblinking with stock bulb taillights and now the new Valenti's.

Valenti are LED...

random thought, have you tried swapping a flasher bulb from side to side? I'd be curious about as voltage read at the bulb too.

Tried that. Is dim on the left side with either new bulb when you switch them.

Last week I hit a pothole and then the blinker worked fine for about 15 minutes. Then started hyperblinking again. Gives creedence that maybe the ground wire needs to be fidgeted with.

Any other contacts that could need cleaned/checked?

Thats a wiring diagram, also make sure the relay under the steering wheel is working properly. That's the relay everyone replaces with LED compatible ones all the time (like myself

)

Valentis do not require the hyperflash relay, they have resistors built into them....

Fixed.

The grounding wire had a little bit of white corrosion on it, scraped it off, lights on the left side were equally bright BUT...... still hyperblink!

So I unscrewed the left signal and took one more close look with a brighter flashlight and there was the tiniest specs of the same white corrosion on parts of the socket. Easily scraped it away with my key. Plugged the bulb back in - VOILA. Works again.

The right signal is probably not far behind - going to clean it as well.
