Hi Scotty, I bought a 2002 Acura RSX with 178,000 miles and has a manual transmission. I have an issue with my high beams. I placed new LED bulbs and when they turn on they are bright for a second and get dim and stay dim. However, when I put regular halogen bulbs they don't turn on at all. Low-beam lights are perfectly fine with both types of bulbs. The battery is new and I've checked the fuses and they are all good. I checked the voltage at the high-beam plug and it reads 13.5v when the car is running. Any ideas on what to do?

Check it under load. I had a similar problem with a headlight and as soon as you put a load on the plug, even a test light rather than a meter, the voltage plummeted way down.
What could cause that issue that as soon as it happens the voltage would drop?
In my case there was a connector where the headlight plug wiring connects into the car's wiring harness that had developed corrosion. Cleaning that up fixed the problem. So you may have something similar going on, a bad connection somewhere in the wiring leading up to the headlight plug or in the headlight plug.

I'll try that out, thank you for the guidance! I'll post if I find anything.
