Dimlighted headlight

My wife just bough a 1997 kia sephia from an auction, without me knowing, anyhow one of the headligts seemed alot dimmer. so i replaced the bulbs and cleaned the inside and outside of the lens. but the bulb is barely on. I really don’t wanna take it to a mechanic it was only 650. so any help would be appreciated

Check connection, between the relay-battery and relay-headlights. Check both hot and ground and hot side. You probably have a high-resistance connection somewhere.

i will try that thanks
