Phantom410

Hello all,

I've had my RX for a number of years, but this one stumped me. My low beams stopped working on me, and the high beams work, but are extremely dim. I've checked most fuses and relays and they all seem okay. I was thinking it might be the actual headlight relay but my new one gives me the same results. Any thoughts? Also, what part # for said relay should i be using for a proper replacement should that be the issue? Can provide images if needed.

Thanks!

Are bulb plugs clean and free of oxidation? You have high resistance somewhere, lowering throughput to the bulbs. Which corrosion comes to mind first.

Both bulbs brand new, contacts clean of oxidation. I should add that when I run a bypass in the fuse box with a single wire where the headlight relay goes, the low and high beams work. Does that indicate both my relays (new + old) are the culprit?
