No high beams - stock lights

I tried searching this, but everything seems to pertain to LED lights but mine are stock (2010 JK).

The other night I switched on the high beams and both headlights went out. The high beam indicator on the dash came on, so I don't think it's an issue with the switch. Low beams work normal, and I don't think the odds of both high beams burning out at the same time are pretty high.

What should I be looking at?

Use a multimeter to confirm power for high beam. Look for corrosion or broken wires. Otherwise try a different bulb...

I have seen people in the past that have installed the wrong bulb and there was no high beam in it. Also in my 2014 the highbeams seem to be too high, to the point where it does look like the lights cut out. (I adjusted the lights down and now they sort of work)

Not able to help much, but what happens when you pull the stem towards you, like flashing high beams? If they work then maybe it is it the stem switch.

Ok... I will relate a story that happened to my dad. He drove from Saskatchewan to British Columbia (about 1400km) and when it got dark his headlights weren't working. When he got to my place, he was mad... started pulling fuses... shaking wires... and breaking stuff in the process.

'Dad', I asked, 'Did you try a new bulb?'

'Bwah! They wouldn't both burn out at the same time!' and he spent another hour f!ing around.

I went and got my multi meter, pulled the plug out of the headlight, and it had 12v fine and dandy. So did the other side.

So how did both burn out at the same time? They didn't. He had probably been driving around with 1 headlight for a month, or six... not noticing the decrease because he's just like that. When the other one finally went... he had no lights.

So before you pull your steering wheel off and start checking the clock spring... either grab a new bulb or pop the connector and use your 12VDC so see what's going on.

Turns out both high beams were burnt out. Honestly, in all my years of driving I've never had a headlight go out, much less both sides, so I was assuming it was some sort of big issue. That's what I get for overthinking.

They do recommend replacing bulbs in pairs for a reason.

If it helps you to make sense of it. I am pretty sure the high beams are used for the daytime running lights.

Well, in all my years of driving, headlights burned out frequently back in the 70's.
