Well the brilliant engineers at GM force you to buy a torx socket to be able to adjust your headlights. (Clearly this is a tactic to force consumers to go to the dealer and pay a guy $110 an hr to do a job that anyone should be able to do--so not one bit happy about this "screw the consumer" mentality by GM's managment). So I bought a socket set for $20, and guess what - neither the E8 or E10 work that comes with the set I bought. (there is no E9 in the set).

So a simple job that should have taken 10-15 minutes of my time, now has over 2 hours involved after the trip to Sears to buy a torx socket set for $20 and my headlights still are not adjusted...

So is the torx socket to adjust the headlights metric or another size? Any help would be helpful.

Its a T15 Torx

Thank you for your assistance. Well being there was so much dirt inside the recessed torx that I could not even tell there was torx T15 recessed for a torx driver to fit inside the head (it is a combo for both a driver and socket), as before I could only see the outside splines being a torx socket would fit.

I still will need the socket size as when I placed a T15 torx driver into the head--it shattered the cheap metal torx head [not the torx driver--but the head itself literally fell apart (not stripped) when I twisted the torx handle] as the head crumbled into pieces. The heads fell apart on both hedlight set ups. Really? GM used to make durable parts, so this is really chapping my hide...

So I need the correct torx socket size which I asked for to begin with and get lucky that the torx head will hold up or otherwise I have to buy a whole new headlamps assemblies for both sides which is riduculous having to do so for a 15 YO truck because of inferior metal was used for the torx heads.

The only thing I find is the reference to the T15... and no reference to the Torx socket, just for reference and for anyone else to chime in you need the black socket one pictured size, correct?

The middle photo is a torx socket. Photos left and right are torx drivers.

The head accepts BOTH a driver and a socket. But like I mentioned the inner teeth of the head broke off. So if I had the outher torx socket size I try that. BTW I tired the E8 and E10 Torx socket, 1 is too big and 1 is too small. So wondering if it's a metric torx socket or a E9 socket???

I know this is an old thread but just in case someone is searching for this info
I linked in here from a google pics search on torx sockets. The socket your trying to find is actually a 12 point 1/4 inch standard socket.



I changed my standard Sierra headlights with some Denali projector lens type and they needed adj.

One thing to notice the Denali headlights adjustment section on the rear of the headlight body is weak and they will crack/break off. [On the original GM headlights, I wanted original lights not the chinese cheap knockoff crap]. That's how I got mine so cheap for $100 for the set and pristine clear lenses then epoxied them back together and covered them with X-Pel Headlight Protection film. 2 yrs and the x-pel is working and lightly sandblasted but can be replaced in a few more yrs without degrading the original lens. No yellowing and the x-pel is harder than the headlights plastic it seems so I may be able to get 5+ yrs before I need to repair anything, maybe up to 10 yrs. [your mileage may vary ]
