2010 Tahoe High Beam question.

Someone who is a career maint / fleet service employee on PPV / SSV will pretty much say something like …. Oh yea, somebody probably pulled the thingamabobber and didn’t add a jumper wire on the hoochamathingy.

Could just be bad bulbs.. I know this sounds too simple.
I upgraded my Yuk bulbs after I bought it.. Less than a year
later I had ZERO high beams.. WTF.. Chased electricity all over...
Dim's were just fine...
Finally PIA pulled my headlight assemblies out and the highs were burnt out.
WTF prob had less than an hour on the highs.. Dims were normal though.
So I put in LED's and they have lasted for 3+ years
