My DTRL stopped working

I just noticed it last night when I went to warm my truck up before leaving a family dinner. I know they were on the day before that. I have the dual amber/white LED bulbs in and I'm confused because the signals will still come on amber but the steady white isn't coming on. I'm sure there is a simple solution, but when in doubt, ask TW

 

Normal DTRL don't come on in park with the parking brake on , not sure but that may be what you are seeing if you noticed them off while warming up the truck

 

You were right of course

I would have never known until now, I did have my e brake on. Let's forget this thread was ever made

 

You DA man OZ...!! Right on top of that one, EH..!!

 

That's so you can have sex in the truck without people knowing
