Brighter LED DRLs? Yup!

[AceTango]

for those of you who have done this, does the brighter DRL have a slightly different color? Or does it just become brighter? I don't really want to have one brighter than the other but I am still on the fence of doing this. If both LED strips are still the same color then I will be more likely to do this.

 

I would make this decision myself based off of pics posted but in my experience with taking pics of my lights i know I can turn on all my off road lights and headlights and everything will look the same in a picture but actually seeing everything in person will result in seeing differences in color

The mod just makes the bottom row brighter and does not change the color at all. I've had it done for about a week and I'm completely satisfied. I do wish someone could figure out how to get the top row brighter. Even with the top row being dimmer than the bottom, the lights look pretty slick at night. Nice white color, with no hint of blue at all. Edited February 11, 2015 by AceTango

So I probed the wires for about an hour, at the end, I failed miserably

 

The bottom rail is "one" rail, the brightness at dimmer state is just ~5v, doing the mod pushes the same pin to full ~11.8v which results the full brightness on the rail.

 

It is possible to get the top row working, it has to be done internally though. I have probed all wires going to the headlight, all are maxed out at close to 12v after the diode mod under the dash.

 

I did this mod for now, but I think there should be slight light output increase if you still use halogen bulbs ;) I really wish the top can be as bright as the bottom too without cutting them open

They will only activate when the truck is in gear.

 

This may be a silly question but have you checked that they do not work when in gear? Or just when the truck is running you walk up front and don't see them on? If they are not activating when in gear then you'd have to get the wiring checked out.

Gotta try this mod seems easy but will see

Well I know that Phil at fastheadlights has something to make both strips come on both day and night at 100% brightness. I just got excited when I saw this thread cause it could've saved me the money from getting him to do the mod when he has my headlights to do a new projector retrofit.

 

I think Phil has been able to create a custom circuit board that allows this to happen.

 

 

Mike, where do I find the kit the Phil has to do this?

 

Thanks

He doesn't have it up on his website yet. I only mentioned it because I saw a pair of headlights he worked on and he did the mod on them and I asked him about it. Not sure when it'll go on the site, would have to talk to him about gettin the board or whatever is needed to make it work.

[Jaykhjr28]

Great, thanks alot. I emailed him from his website.

How come I can't see any of the photos?? I'd love to do this with my GMC but I can't see any of the pics, all it says is photo not fount, click for photo, I tap on the pic and nothing takes me to a blank page..

Anyone know what I gotta do to change that??

[sjraley]

Did anyone save the pictures? I'd like to do this but want to make sure I'm wiring the right one. Any help!

Can someone pleaseeee take new pics of where the diodes go? For some reason the original pics from the 1st post are not showing up.

Over and Jarod from Gen5 just completed a harness for my 2016 Sierra to keep the C shape LED DRL's on full power. They are available for the SLE with the HID's and the SLT's as well. They are plug and play, no adding diodes are altering the factory wiring harness or BCM. They are $50 for the set.

Update: Harness works on SLT LED headlights. Waiting on the SLE mid.
