These are the only ones they told me would be suitable for drls and blinkers on my 2010 Yukon denali xl. But do far they light up and work great as blinkers and hazards but they won't stay on like my old ones did as drls. Anyone know why this is happing ? Thanks

Are you trying to use those as switchbacks?

If you got the 3156 they won't work that way as they are single circuit.

Btw, I'm a little confused ... I thought the Yukons didn't have a separate drl and that they just used a dim setting on the headlights for that function.
