2004 Acura RSX - Strange light issue, please help troubleshooting Sign In

Hi all,
I hope that someone could help out.
This is a 2004 Acura RSX-S. After uninstalling the front bumper, I removed the headlight projectors to test some new LED bulbs that I recently bought. They didn’t do as much light as the halo bulbs, so I discarded them and reinstalled the original halo bulbs.
Both lights, the low and high beam are not working properly on the passenger side, while they are perfectly working on the driver side.
1) First issue is that on the passenger side they are not bright as they should, the light is really low (check picture below). Also, I need to plug both lights into the connector in order for them to turn on. If I plug only one light, they don’t turn on. This problem doesn’t happen on the driver side, where I can plug only one light at time and they turn on.

2) Second issue is that when I turn on the high beams, both low and high beam shut off. Check the picture below. The driver side is fine, while the passenger side lights are off.

I did the following testing:
- I checked all the fuses one by one and they all seem to be fine. Also if a fuse was broken, then the light wouldn’t turn on at all.
- I removed the light bulbs from the passenger side and installed to the driver side and vice versa. Same exact issue. Thus, the light bulbs seem to work perfectly fine. I guess that the issue is somewhere else and I don’t know where.
What could cause this issue? What other components should I check/replace?
Thanks in advance. If you have questions, please let me know and I’ll answer promptly.

Back pin the ground wires of the sockets at the connector and run a jumper to ground. See if they are doing better. If so you have poor ground on that side. You would fix that by finding the ground point at the body and taking it apart, grinding the steel it bolts to nice and shiny and then bolting it back up, with something over the top of that to seal it from weather. Do you have a multimeter and some experience with using it?

Just curious, but why did you remove the bumper cover to switch out the head lamp bulbs?

Check G201.

Thanks for the prompt response. I will follow your suggestion. I have a digital multimeter. I don't know much about it. All I could understand is how to read the Volts.

Excellent question. I removed the bumper because the LED I bought are fatter than the stock halo and they didn't fit. I made a bigger hole to insert the LED, just to discover that it wasn't as powerful as the stock halo Frown. Also, I always wanted to learn how to remove the bumper to install fog lights, and to possibly paint the headlights, making the metallic plastic black to match with the car (not the projector itself, but the outside of it)

Thanks, you were right. The ground cable was bad. I couldn't do it myself for lack of knowledge. I couldn't locate it. I took the car to a mechanic he did it for me.

Glad to hear its fixed. Sometimes when you're in over your head the smartest thing to do is seek out a pro. I've seen others keep going blindly and do some expensive damage, so good that you know your limits.
