One headlight dipped even after bulb change?

I thought the bulb was bad so I changed it but my right headlight is still dimmed in comparison with my (good) left headlight.. what could cause this?One headlight dipped even after bulb change?I would bet that you have ground wire on that side that isn't making good contact. I would start there, more than likely a body ground near the light.One headlight dipped even after bulb change?Check your wire connection for the light. It might be corroded or just loose causing a bad connection. Also try cleaning the glass.One headlight dipped even after bulb change?Probably a poor electrical earth.
