LumaWerx™ 4114K GM High Power LED Running Light Bulb – LW30 CREE



Product Description

Bright – The LumaWerx™ 4114K LW30 CREE LED bulbs are the brightest replacement LED bulbs you can find today with American made CREE LED chips giving you a total of 30 watts of output while drawing 1/4 of a standard incandescent bulb. Each bulb produces a massive 680 lumens, the most amount of light output and the longest lifespan offered for any plug-and-play 4114K LED bulb.


Installation – Specifically created to be 100% plug-and-play for all applications. No conversion required, simply remove the old bulb and plug in the new LED and you’re done! Offered in a variety of colors so you can choose just what is best suited for your application.


Exclusive – These bulbs are specially designed for use in GM vehicles to work properly with their voltage spikes which occur in the daytime running lights/driving lights and cause normal LED’s to burn out. Our LED’s last over 50,000 hours and have zero issues with voltage spike, guaranteed.


GM Spec’d – Common vehicles which need this style of bulb: Cadillac, GMC, Hummer, Chevrolet and more. Not sure if this is the right bulb for your vehicle? Find out here. While the bulbs produce an astounding 30 watts of power, their draw is far less than a stock bulb so there are no worries of melting housings or burning up wires as the LW30 draws less and produces less heat compared to a stock 4114K bulb.

  1. :

    I bought these for daytime running lights and I've got to say I am impressed. These are really bright. I got the pure white and they are a very close match to my 6000K HID's. The Sylvania 4114's put out 490 lumens; these put out 680 lumens. These come with a two year warranty as opposed to a one year warranty. Simply impressive.

  2. :

    Put these in my H2 Hummer and have tried about 10 other types of bulbs, none of which worked so I assumed this would be the same with these, it was not! 3 years later, still going strong!

  3. :

    Glad there is someone who makes a true 4114 bulb. I was using 3157 base bulbs and couldn't figure out why they kept burning up, friend turned me on to these and so far haven't had any issues, nice crisp bright white too.

  4. :

    Ran the SMD style in my Silverado and decided I wanted something brighter, these are MUCH brighter. At first I did not think they would fit as they were very tight to snap in, I beleive this was from the sockets were already super burnt from the stock halogen bulbs. Been running for 2 years now and no complaints, super bright, very nice pure white color.

  5. :

    super bright white, just what I was looking for, waited to see if they would last before leaving my review and sure enough, 12 months later, still going strong (11 months longer than any other bulb I have tried so far)
