Just noticed a hyperflash when turning left today. Got out and took a look, and all the bulbs are fine---the front marker turn lights flicker to signal left, but the rear taillight does not flicker (even though the bulb is fine).

I have regular halogen bulbs in the front 2 turn markers, both side markers, and in the back 2 taillight bulbs. I have white LED's in the back reverse bulbs (caused no issue for reverse camera pop out), and LED's for the front headlights and fog lights.

Its been setup this way for a while now, no changes made. Just out of the blue today, a hyperflash ONLY on left turns (not on right). No bulbs burnt out.

Any ideas?

 

take the bulbs out and clean them and the sockets? might find something overlooked.

 

You could spend hours finding a shorted wire, or simply swap your RR with LR, to test the dual filament bulb.

 

They use hyperflash on the Millennium Falcon, didn't know it was an option with the H3???

 

The Millennium Falcon had a hyperdrive which when working could propel the ship into light speed.

 

Does the left rear brake light work? The hyperflash is telling you that a bulb (or filament) is burned out.
