Crummy headlights - Can't see, need upgrade
My old 2007 GMC has never had the best headlights. Driving from Lethbridge to Calgary last night I was really cussing them. Old original factory headlights and I cannot see worth a darn. They are...

Hi,
Driving lights during day has been a requirement in Canada since 1989. I wish it would include tail lights, too.
Since OP has a 2007, yeah it would apply.
The question now becomes is his DRL using the headlights at a reduced power level?
If so, store bought relay kits most likely will remove that function, not aware of any that add or include DRL but perhaps there might be..
Generally for headlights the manufacturer uses a resistor in series with low beam filament, dropping the voltage and brightness for that function.
Turn the headlights on via your dash switch and the resistor is bypassed allowing "full" voltage to headlight..
To restore that function with a relay kit will require a SPST relay that when headlight switch is off the NC contact will connect the resistor to the headlight..
Of course if OPs DRL is done via separate "driving lights" then premade relay kit should be OK to use.
