vled LMZ led headlights

[Skeeter McSkeet]

Are the caps on the Sierra headlights necessary at all?

You don't need them to make them fit, you do need them to help the bulb function properly with its cooling blades/fan whatever the tech word is for that portion of the bulb is. I'd recommend them without a doubt, it's still a little tight in there even with the extended caps. With the extended caps you can put all your parts inside the cap itself instead of mounting them on the outside. But, the Jury is still out on if putting everything inside the cap is going to be good or bad yet lol.

Oh My God, These Vleds are expensive. I'm happy with these 2k Lumens 20w 9006 I got from ebay.

Finally ordered my D2S collars so I can test these bulbs out in an FXR projector [emoji106] will let yall know how that goes!

Any pics of the output?

 

The LMZ's are rated to last 30,000 hours. If that holds true, I'd say the price of the bulbs would be less than the total you'd spend replacing the OEM bulbs over that same span of time.

I'm waiting for a replacement bulb from VLEDS after it fail with less than 30 hours

Got a link to these?

Damn!! Did u have to send the bad bulb in? Any idea what the issue was/is? Looks like you have a Silvy from your pic (I'm on tapatalk right now), did it fit in there without needing a modified dust cap?

No, you don't have to send them in. I noticed when I turned the fog lights on that the bulb was glowing blue, almost like a halo effect. I shut them off and turned them back on. However, that bulb never came back on.

On another note, I'm going to try to stop by and talk to my buddy at the dealership tomorrow to get the BCM flash and new bulbs in from the TSB set up. Can't wait to see what these do with the new update.

Hopefully it was just a bad bulb man. I've been paranoid as is right now about leaving the ballasts inside the assembly, and I know mike1220 has been even more so than I haha. Just trying to figure out what may have caused it if it wasn't just a $125 dud.

Whats this update all about?

[Skeeter McSkeet]

Whats this update all about?

It's a TSB that was released on 2-27-15 (I think), it's supposed to address the poor OEM headlight output. Involves flashing/updating the BCM to give more voltage to the lights as well as a new upgraded bulb made by a company called Volsa. The TSB number is PIT5374 if you want to call a dealer to ask about it.

 

This thread has all the info you need on it, first 400 posts or so are useless, the last 50 or so have the meat and potatoes.

you still have the vled lmz's right? are you going to get this update? if you stilll have the lmz's, do you think this flash well help the output of them? cut down the life of the lights??

Yes I've still got the LMZs in, I plan to take them out before I go in for the update. I'm just guessing, but if the extra voltage the update sends to the lights makes them brighter, I'd say it would help these as well. I don't know the tech specs on the LMZs or if there is a certain voltage that can harm them, but I'd say it couldn't do anything but help them.

 

Anyone here have LMZs installed with a truck built AFTER the dates listed below? Trucks built before those dates are eligible for the TSB, ones built after already have the update.

 

Here's the run down of trucks eligible for it:

 

Here is the wording of the TSB for applicable build dates:

 

• For vehicles built before 12/23/14 at Flint Assembly (11th Vin Digit "F"), 1/13/15 at Silao Assembly (11th Vin Digit "G") or 1/16/15 at Ft. Wayne Assembly (11th Vin Digit "Z"), reprogram the BCM with the latest calibration available in TIS2WEB starting on 1/12/2015. The new BCM calibration will increase the voltage to the headlight bulbs in both the low beam and high beam selections.

   

  Important: All vehicles built after the above dates already have the new BCM calibrations and the BCM reprogramming does NOT need to be performed.

Let us know how it goes and be sure to take some before and after pics. Would be nice if you had a meter like Spurshot does so we could see for sure if there are any actual improvements in light output.
