Running Lights Off with Turn Signal...

[clowe1243]

Any of you guys hate the fact that the running/driving light on the side of the turn signal turns off when flashing?  Just makes me think the truck looks retarded when I obey the law.  I remember with my Avalanche, a diode had to be crossed in the fuse box to keep them on.  Anybody know or done anything?

On my Sierra SLT I don't believe the DRLs get turned off during blinkers....    Not sure if they are rated bright enough to not be distracting, so they don't turn off, or what the difference is... but they stay on.

So here's what I learned about my 2020 Silverado 1500 LT Texas Edition...

 

1) When it's day, and just the DRL's are on, they are at their brightest. When the turn signal is on, the DRL's TURN OFF.

2) When it's night, and the lights are on, the DRL's are dimmer. When the turn signal is on, the DRL's DO NOT TURN OFF.

 

There is a federal law (FMVSS 108) that states when the DRL's can stay on and when they must turn off. Here is a good read that I found... https://jalopnik.com/heres-why-modern-cars-turn-off-one-of-their-lights-when-1792394567

 

So, I ordered the quoted harness shown above. After installing, I checked all lighting functions and everything worked as normal, and the DRL's DID NOT TURN OFF...even in the day.

 

And to hopefully not be out of compliance in any way, I ordered these turn signal bulbs from Lasfit. They're designed to avoid any "hyperflash" errors.  https://www.lasfit.com/collections/7443/products/lasfit-7440-7441-w21w-led-turn-signal-lights-canbus-error-free 

 

So now, my DRL's stay on ALL THE TIME, and my turn signals are BRIGHT AS HELL without any errors. I'm happy with this modification combination.

Leaman Griffin has a YouTube channel. I've learned a LOT about my truck from watching his vids. This is the one about the turn signals...

I'm hoping they are able to come up with a solution for the high country version... The LED signals on the truck must be bright enough to not require the DRL's to turn off...

This is one of several reasons why I went with a Sierra.  It doesn't matter trim level (LED or incandescent) the DRL doesn't shut off.
