A very bright Cool White Dome Lights replacement festoon.  This is a CANBUS LED.  CANBUS LEDs are required in certain car installations so the light does not throw an error code in the cars computer.  The CANBUS tricks the computer into thinking this light is an incandescent.  Multiple OEM Applications.  We have added this for Jeeps.  2012 and newer Jeep JKs require a CANBUS dome light or the computer will not let the map lights turn off.  Pair this festoon with two T10-5-5050-CW and convert your Jeep Unlimited to double the light output and Cool White light without the heat.  Can also be used with any JK 2006 and newer.

  1. inconsistent color temp 4 Star Review

    Posted by on 3rd Oct 2018

    Not too excited about these lights. I'm using them for interior light in my Jeep patriot.Early this year I bought a pair for the front dome light. Terrible mismatch of color temp. Customer serv. excellent. They sent another overnight to get a better match. Quite happy then. Now one died, so I just ordered a couple of new ones (1 for a spare) (I thought LED's would last longer). Now I have THREE different color temps. Looks bad in the front light which uses 2 lamps. These are fine for a single lamp fixture but I've bought some lights from another source That are WAY brighter with matching color temps. Sorry M4....

    M4 Note: If something failed from this year, they are under warranty for two years, contact us. We will research your orders on color temp.

  2. Bright light, excellent service 5 Star Review

    Posted by on 16th Jan 2018

    I bought a pair of these Festoon lights to replace the originals in the front dome light of my 2010 Jeep Patriot. Had to spring in the clips a little for a good fit.
    I had a little temp difference. One very white, the other a little bluish. I had noticed a minor difference on the package labels & I Emailed them about trying to color match lights when pulling an order. I wasn't even asking for a replacement & it wasn't really a complaint. But, IMEDIATELY, they sent another light so I could match them.
    Lights match, bright white. Much easier to see in front seat area. As far as dim decay when they turn off...Just like originals.

  3. Better Than The Original Bulbs 5 Star Review

    Posted by on 20th Nov 2016

    I bought one of these for the cargo light in my Wrangler. I have a net covering one side of the dome are and this light bulb is still bright enough to light up the cargo and surrounding areas.

  4. Brightens things up 5 Star Review

    Posted by on 5th May 2015

    I purchased this product for my truck and for the interior light for my refridgarator in my motorhome. I made a big difference in both over the standard bulbs that were there. Great product, fast service.

  5. A good product 4 Star Review

    Posted by on 23rd Jan 2015

    These bulbs work pretty good but are a little blue for my taste.

    I prefer the natural white color in almost every application.

    These bulbs do the job without the heat or current draw so I consider them to be superior to the bulbs I took out (which had gotten hot enough in the last 7 years I have owned the truck to show darkish-burn marks on the adjacent plastic).

    Alas, if they only came in Natural White....

  6. So So 3 Star Review

    Posted by on 28th Jul 2014

    Installed this in my 5th wheel fridge. At first, when the fridge was empty, I thought it did indeed look brighter than the original incandescent. Just got done stocking the fridge for a trip and am now not that impressed. The food creates darker shadows giving the impression the bulb is not as bright as it should be. Will use much less battery juice though.

    M4 Note: This is not the recommended 42mm LED for refrigerator use, it is designed for dome lights that use festoons. The item you want for a the fridge that uses a 42mm festoon is FESTOON-211-2-CW
