Wow thanks very much for that large inclusive list!

 

I wish there was a list correlated in yours, as to which are the easiest and least expensive to swap out to LED, Halogen, HID (others technologies?). If anyone has already covered this elsewhere other than the aforementioned individual forums please let me know.

 

But before I start, is there a rule as to which lights are upgradeable to LED, Halogen, HID (any other technologies) without breaking any DOT or other laws?

My lights from day one where fine, compared to the projector style headlights. My main issue was the yellow looking color of the stock bulbs but after I changed to the Phillips Crystal Vision I can ho

Thanks again the Phillips 194 arrived yesteday and can confirm they work perfectly in a 2017 for plate lights. Eagerly awaiting the two sets of Phillips 921 and 1N4004 diodes to arrive.

There are no real blanket laws other than that lights on the front of the vehicle should only be white or amber/yellow, side should only be amber or red, and back of the vehicle should only be red or, if it is an emergency flasher or turn signal then it can be amber.

 

Those are my general rules for lights. Outside of that cops around here start to give you trouble as long as you do not have an excessive amount of light coming from the light source.

 

I would check your local laws for specifics about any lights you want to change. You can change pretty much any lights from halogen to LED as long as it still operates as it should, ie it doesn't have a hyper blink.

HID's in non-projector housing are illegal...dunno how it's enforced unless it's for not having all required OEM equipment in working order.

 

All auxiliary lighting (light bar) should be dimmed with high-beams to oncoming traffic.

Does anyone know if a modified 894 bulb (37.5W) would cause any issues if it was used to replace a 921 (18 W) reverse light?

For CA members, here's the vehicle code. Some flexibility, but no way a 100 watt LED bar is legal here for highway use.

 

From my read, none of the HID kits or aftermarket manufactured projectors are approved for CA use. You could make a case for using an OEM (real one) HID projector system off of another type of vehicle.

It might blow the fuse. The fuse should protect the wiring.

Anyone use these on a 14 Sierra? It says available in popular sizes such as 9006....

Thanks,

Mark

A standard 9006 produces 1000 lumens according to Daniel Stern's chart. The stock bulb in a 2014 Sierra is a 9012 and it produces 1870 lumens (87% increase over a 9006). A 9011 bulb (easily fit to a Sierra) produces 2350 lumens (135% more than a 9006). Why would you go down in light output?

Got to this thread, page 14. There's a complete explanation of how to fit a 9011. No mods to the truck. The bulb gets some clipping and shaving of the tabs and socket. 10 min job tops. A 9011 is 2350 lumens or about 25% more than the stock 9012 bulb. It's not a big change in light, but it's an improvement.

      2026 DENALI 6.2L

      By pyoung62 · Posted

      I agree with Tim.  As tech heavy as engines are these days, no way I’d be an early buyer of the new 6.6.  Of course, I bought my ‘26 Denali w/the 6.2 after dumping my Tundra with it’s defective 3.5 liter imploding engine disaster, so I’m a little gun-shy.  That said, my 6.2 has been rock solid.  I don’t drive it like I do my BMW Z4 M40i, but I don’t baby it either.  I got a V8 for a reason.  But I’m averaging 18 around town and 22 highway.  I have seen 24 highway as well when I wasn’t loaded up heavy.  Considering my Tundra with the twin turbo V6 only got 14.5 in town and 17 on the road, I’ll take the 6.2 all day, every day.  If I were you, I’d grab a ‘26 while you can.  Inventories are probably gonna start dropping and I’ll bet the deals will start looking sweeter as well.

      Can you add a 360° Cameras hard button to a 2021 Sierra?

      By ShowMeShooter1332 · Posted

      I am curious if anyone has figured out a way to add an hard button AUX or 360 Camera switch to the center row of switches. I have a 2021 AT4, and want to split the hill decent button and add a 360 camera button so that you don't have to go into the center display and locate the camera functionality, etc...   My father's 2024 Yukon XL AT4 and it has a hard button, see below. I found this thread on the Yukons, but it seems like there may not be a part number for the 2021 sierras. https://www.gm-trucks.com/forums/topic/255339-adding-hard-button-for-camera-on-2021/ Anyone else figured this out. Seems like it would need to be a custom switch!   I am getting ready to install the auto stop/start eliminator, so would be nice to knock them out at once.     Upvote1Downvote0Go to comments

      Oil Consumption

      By Chuck FB · Posted

      Through the years it hasn't been my typical method as I tried to drop oil on an engine that was hot from having been worked, however that was not always practical and had to fire up a unit and let it warm up reasonably well and drop the oil when I had the time to do it but am referring to not only vehicles but a variety of farm equipment and highway tractors etc. However on a vehicle where one is crawling under it and the exhaust is nearby to ones body and if wanting to pull the plug without danger of being hit with boiling hot oil or attempting to remove a HOT oil filter, its sure safer and easier to not have everything smoking hot and can remove the filter right away when under the vehicle and let it all drain. Of course its not the end of the world if a bit of oil stays in the engine that might have eventually found its way out, I like to get out as much as possible but any oil changes that take place in shops would rarely be sitting around for very long at all before the plug is thrown back in and filter slapped on and oil poured in and sent out the door quick like. There would be very little time spent ( assuming they even did it ) in starting the engine with oil to fill the filter, then waiting to verify the level on the stick. A good reason to check ones oil level shortly after a shop changed the oil on a vehicle just to make sure its correct and to look under for any oil around the drain plug or filter.
