Headlight dim

I just replaced my headlights because the passenger side high beam wasn't working. I replaced them with Rampage H4

Now the passenger side highbeam still isn't working, but tonight the low beam was dim.........

Any ideas?

I did the delta h4 conversion. Mine did the same thing shortly after I did the swap. My drivers side lamp was not bright and then the Highs would not light up. I was mad that they sent me bad bulbs. I did not do anything for a couple days and then everything worked. Cant explain it.

Clean the plug for the headlights. Get all of the old dielectric grease out and clean them out good with electrical contact cleaner. Scrape any corrosion from the contacts and apply new dielectric grease. See if that works.

Check your headlight ground wires clean and tighten.
