Hi everyone! I have a 2018 Toyota CH-R 1.8 hybrid, bought new, currently at 86k km. Lately, I’ve been having an issue where the high beams won’t activate. When I switch to high beams, the lights stay on low beam, but the blue high beam indicator on the dashboard still lights up.
My car has automatic high beams, but even with that feature turned off, the issue remains. I’ve tried replacing the bulbs and checked the fuse, which isn’t blown, but still no luck. I installed an aftermarket tablet for Apple CarPlay around five months ago, but the high beams have worked fine until just recently. Not sure if it could be related. Any ideas?
Are you sure you’re using the correct bulbs? Your car should need a 9012 (dual-filament) bulb that handles both high and low beams. It’s possible to install the wrong bulbs, which might only provide low beams.

I’ve been using LED bulbs, and the high beams worked fine for at least 11 months. Now they’ve stopped working. I put the original halogens back in, but the high beams still aren’t working.
Check for corrosion on the bulb connectors. Are both high beams not working, even with the original halogens? And just to confirm, the automatic high beam setting is off, right?
I had an issue where both low beams didn’t work, and it turned out the bulbs went out at the same time. I’d also look into the wiring to see if anything’s brittle or if the LED bulb resistor could’ve caused any issues.

Both high beams are out, even with the original halogen bulbs back in. And yes, the automatic high beam setting is off. The LEDs worked perfectly until a few days ago, so I’m stumped.

Did you check the power going to the high beams with a multimeter, and verify that the high beam filaments in the halogens still work? Also, double-check the fuses for the high beams.

Here’s a thread on Toyota Nation that might help troubleshoot:
Is the automatic dimming feature enabled? (The AUTO button) Sometimes if it senses other lights, it won’t let the high beams turn on. Works fine on a dark road, though.

The automatic function is off, and it still won’t go to high beam. It just stays on low beam, even if I try to flash the high beams.
