Alpharex headlight install
hello,
I just bought the alpharex head light for my 2019 f150 xl stx package.
tried to install the the blinker assembly socket and bulb to the alpharex housing.
but the stock socket has 3 interfaces(hexes) and new headlight housing has 4 interfaces(hexes) so it does not fit.
I tried to do research to sovle the problem but looks like i am the only one who have this problem.
if anyone who did install this unit on 2019 f150 xl stx, Can you guys tell me how to put this in to the new unit?
thank you
The 2019 trucks switched to a different bulb and socket for the turn signals from the 2018's. You will probably have to buy the older style and splice them in to get the new lights to work.

I brought that up in the main thread about these headlights because I had the same issue on my 19 XLT. I used a box cutter and trimmed a bit of plastic from the housing socket until I could force it in. Kind of a pain, but it's not going anywhere.
You don't have any issue with water going in or the socket comes out or anything?

Nope, it fits in tight. It took a lot of force to get in, so it's definitely not coming loose. I've had the headlights for 4 or 5 months now and no water in them.
