one of my head lights went out recently and my friend gave me an extra one that was lying around. i looked at it to check if it was the right size ( mine being 9006) and it just says 900X on it. i dont know wtf that means so i stick it in and it works fine. is this damaging my wire or anything else in any way? TIA

 

Its not gonna damage anything, it just will work or it wont work

 

excellent... thanks for your help
