22" GMC Accessory Wheels - Factory setup, probably my favourite 22" design!!

Ya, I'd also like some more info on this. Let's put it this way: Scenario 1: Truck drives 60,000KM in daytime only = uses DRL's only. Scenario 2: Truck drives 60,000KM at night only = uses low beams along with DRL's. What would the difference on "wear" be? The diode isn't increasing voltage or power, all it is doing is sending the signal for them to turn on.

Sorry, I also did the reverse/cargo light diode mod at the same time. Now when I unlock I have reverse, cargo and box lights on. And I'll also have the cargo light on when the truck is in reverse.

I think it's more than just supplying the top row with more power. If I'm correct, the bottom row has two sets of LEDs, 1 set used for night time parking lights and then both sets are lit during the day causing them to be brighter. If this is true, then the top row only has 1 set of LEDs so technically they can't get brighter unless you add more LEDs.

I really wish it did but unfortunately the top row only has one functionality, and that is to be lit at that brightness only at night.

No additional light output. Looks much better at night. Along with others, I hate the dimmed look of the LEDs...knowing that they are way brighter in the day time.

They are connected to the Low Beam Pins so they will come on anytime the low beams are on. No difference on the road as these are not high power LEDs - they do not have high light output, only for looks. Stripe on the diode goes toward the DRL as that will prevent the flow of electricity from the DRL circuit to engage the low beams in the daytime. I will have night time pictures after I install my HIDs. Yes they will stay lit when the high beams are activated. These connectors are located in the BCM which is under the driver side dash.

To all the GMC guys...I've got the fix! Firstly, just want to thank @spurshot for inspiring me to put this into motion. Ever since I saw the 14+ GMC's, I thought to myself hmm...I wonder if it's possible to make those bright DRL LED's run the same at night. I probably wouldn't have dived into this if it wasn't for Spurshot's How-To on the Fogs w/Highs as I used the same idea with this. So here it is, using the same 1N4004 diodes: BCM X4 (Black Connector) Pin 1 to Pin 7 Pin 2 goes to Pin 7 on BCM X5 (Brown Connector) See pictures below for the schematics. BEFORE & AFTER And yes...I'm putting in HID's this weekend. Just picked up a 2015 Denali CC 6.2L/8spd in exchange for my 2014 High Country and the mods are still in progress! Enjoy

My HID headlight bulbs install on a 2014 Silverado: Parts used: (1) 35W H11 HID Kit 6000K (1) Relay Harness (2) Error Cancelers / Capacitors Tools used: Utility knife 3M/Double Sided Tape for mounting ballasts Side cutters/pliers to snip end of zip ties Zip Ties Retainer Clip Remover/Flat Head Screwdriver 10mm/7mm socket 3/4 Spade Bit/Hole Saw Impact/Drill [/url] [/url] 1. Remove Air Box: Air box is clipped in so just give it a good pull and it will pop out [/url] 2. Wire Relay Harness: power to (+) to battery connection, ground to (-) battery connection 3. Remove two clips holding in cover behind headlight and remove dust cover from headlight, unplug bulb and remove. 4. Using 3/4 Spade bit, drill a whole in center of dust cover. 5. Insert bulb, pull wires through and install grommet that comes with bulbs. 6. OPTIONAL - I used Rubber Butyl Tape to seal grommet from moisture (you can use silicone, putty or just roll the dice) [/u 7.Install HID bulb into headlight. Connect other wire to Factory Plug (picture shows it's reversed polarity, since this is a DUAL relay harness, you'll plug it in red to red and black to black) then re-install dust cover. 8. Error Cancelers Install male plug (coming from dust cover) to female end of Error Canceler Install male plug from Error Canceler to female plug of relay harness Install male plug from relay harness into ballast [/url] 9. Mount Ballast - apply double-sided tape to back of ballast. I installed ballasts next to headlight on rad support/frame 10. Run remaining two wires from relay harness to driver side. Repeat Steps 3-9. 11. Zip Tie all wires and tidy up the install to your liking. TROUBLESHOOTING 1. Headlights don't come on at all: Check power and/or ground wire. 2. One headlight turns on but not other side: Check connections and ensure ballast is plugged in. 3. Headlights work but when I start the truck, they turn off: You probably don't have the Error Cancelers installed/wired correctly. 4. Headlights work but the relay makes a loud buzzing noise: See #3 For the courtesy of others and to avoid confusion and clutter, please PM me or feel free to email me directly at [email protected] for any questions or troubleshooting issues.

I have the same issue. Very little moisture/fog in the lower (high beam section) of my Silverado headlights. Also saw this on the Sierra A/T I test drove. Goes away almost immediately after lights are turned on. I'm thinking vents somewhere near the very bottom. I'm not too concerned. If the whole headlight fogged up, then I'd be at the dealer

Worked for me the first time! Thanks!

Yeaaa! I got one of them too. Lets see another pic!!

2009 Silverado LTZ WDE with my Yamaha Rhino - only pic I have of it hooked up to the truck (its now painted white diamond, has HIDs and a nice sound system). I plan on buying a boat for the summer time, will post pics of that later on!
