2014 Sierra/Silverado Bulb Sizes

[DenaliDually]

I have 50 watt from TRS with the FXR projector. I wouldn't run them before because they were yellow. I don't run them now as they blinding people, but I'd like to be able to use them in Fog.

 

I talked with VLEDs today and I can't put a relay to control one side of the light, so I will be making a color with a reflector to mount on the lights to keep the cut off low and usable. Got to many other things going to do it right away they way I want. I might use the lathe to make a quick set from bar stock and cut half to get started this weekend if I find some time. I want to get to a mill to make a sharper cutoff for the final.

I agree with your opinion of the light spread on your fogs. I'm looking for a traffic friendly, yet effective fog option and I think you're right on track. Could you take a pic of the bulb before you install it to show how you cover the one side? Also, on my gmc there is minimal room behind the bulb and most of these bright led deals have cooling fans on them so clearance is a concern of mine. Any issues with yours??

I have the trs projector and 50 watt hid kit sitting on my work bench but want to do the fogs at the same time... can't tell you how anxious I am to do what gm should have and get the lighting in this thing back on track.

Thanks in advance, good looking set up you have there.

Check out my gallery for LED foglights. I have not road tested yet as it is appart for other customizing.

The problem with HID and LED bulbs in the stock fog housing is the bulb length. The stock 5202 bulb sits deep in the housing which is what give it the great bream spread and brightness. The HID/LED bulbs tend to be longer and sit further towards the lens which changes the beam pattern making it worse.

 

Until someone comes out with a similar bulb to the stock one there will not be much hope for the stock fog housings.

VLED LMZ bulbs are adjustable in depth. Give them a try. I have a set coming in for my headlights and Crf450r420 has them in the fogs of his Silverado already. Edited January 28, 2015 by Mike1220

Do you have an update on how these work?

There's some pics up on this thread:

Toward the end of the thread I have some pics of the LMZs in a FXR projector.

I have not changed mine. But I do know that if you try to change a light that has to do with the blinker system, then you will get the hyper blink and then a message on the DIC saying that there is a left/right turn signal error. I'm surprised GM didn't put LEDs there stock. Many other manufactures are already switching to tail light LEDs, but since we are talking about trucks, I think it's just becuase trucks are not necessarily a family or DD vehicle, however it does seem that they are making their way to the category

Hey Mike,

 

I got a set of the Eagle Eye Lights and they have the boxes which I thought would have been some type of correction for the system, but I'm getting a normal blink for the first few seconds then a hyper blink and the message on the DIC with the signal error, so what type of load resistor are you referring to in the post?

[carthman]

Yours may be defective. Mine worked out of the box with no problems. Just FYI

I searched through this topic and others but couldn't find a definite answer. For the front turn signals / parking lamps on the Silverados, are the sockets standard or CK?

[billybob denali]

I think I've read all the comments on changing the stock bulbs for the rear brakes, side lights and front blinkers with LEDs.

I think the rear stop/turn are: 7444 or 7444LL

front turns: 7443 or 7443LL

licence plate: 194

These seem to be available from many sources, but I'm more concerned with the low voltage and getting the

hyper-blink. Is there an LED replacement bulbs that have built in "choke" to stop thjis hyper-blink or will I have

to figure out what to use and where to install this item to stop the hyper-flash?

Does the "LL" in the part number mean anything when using LED replacements? I can't find replacements with

LL suffix?

any assistance would be greatly appreciated...

[quise2024]

Ive went thru but don't think ive seen an answer to my question

 

 

I want to replace my stock halogen bulbs with LEDs, is this possible without any type of conversion/kit. Hoping its a simple plug and play, like changing to another halogen bulb.

 

 

 

Thanks in advance

[Victor Ferreira]

The LL is for "Long Life". Means nothing in the LED department, since all LEDs are long lasting.

 

As for the choke, VLEDs sells a flasher unit for $20, to replace your stock flasher in your fuse box, and stop all hyper blinking. This eliminates the need for load resistors.

Thanks Victor for the answers on LL & load resistors... quick follow up question, with the Denali w/ the brake controller option,

would the VLED's flasher unit be necessary? Just not sure with that package, the truck came with a H.D. flasher? Truck DID not

come with the trailer package.. just the brake controller???

thanks again

Billy, I really do not know. I would guess yes, seeing as the flasher unit is essentially an electromechanical circuit in your fuse box. It's basically a fuse, of sorts (but I may stand corrected as I'm not exactly the brightest when it comes to electrical stuff).

 

Cheers!

Threw in LEDs for reverse lights tonight
