How to stop JK Jeep Wrangler Flickering LED Headlights

Jeep Wrangler JK Anti-Flash LED Headlight Wire Harness

This is a harness made by that solves the flickering problems when installing LED headlights in the JK Jeep Wrangler.

One of the most popular things happening in the Jeep market right now (other than Vision X LED Off Road light bars) are LED headlights. Several companies make a light that will fit the opening of the Jeep that uses a 7″ round headlight housing, but nobody makes one specifically for the Jeep. This is a problem because the JK Jeep Wrangler (2007+ Models) use a special CANBUS functionality built into the lighting circuit. This is a good thing because it is a more intelligent design to control the lighting but it makes modifying the headlights a difficulty. This is how to fix the flickering problems you will encounter when trying to install LED headlights into your JK.

Without doing any modifications to the wiring, if you install LED headlights, like the JW Speaker 8700 Evolution, or the Truck-Lite 27250C the lights will flicker, flash randomly or strobe. This can cause headaches for the owner of the product because it will seem like the product is defective.

Back To The 50′s Car Show – Halogen Sealed Beams Everywhere!

back to the 50s

This custom low-rider was getting lots of attention even though it had stock sealed beam headlights!

This past weekend was the 39th annual Back to the 50s car show held at the Minnesota State Fair Grounds in St. Paul, MN. I got to go for a day and see everything and I must say the event was a blast! There were big name vendors like Chevrolet, Rousch, Ford and many smaller local vendors like Union Speed & Style and lots of flea-market style setups selling all sorts of automotive goodies! It was just incredible to see so many restored classics, hot rods, street rods and wild custom muscle cars. Arguably the biggest attraction for myself was trying to spot the different lighting upgrades these enthusiasts were doing to their classic domestic rides. It was unfortunate to see so many cars with stock halogen sealed beam headlights though. The vast majority of these vehicles had stock headlights, tail lights and interior lighting. It was only a characteristic of the nicest of all vehicles in attendance to have upgraded headlights.

Back To the 50s

Crowds of people watching parades of classic cars!

I noticed a trend throughout the entire show, that was if a vehicle did have upgraded forward lighting, it was a stock-style composite housing with a blue halogen light bulb inside. I did not see a single HID conversion kit fitted car, or any type of radical LED headlight. I thought for sure there would be SOMEONE there with some crazy headlights, I must have just missed them. The second most common site to see on these cars was some type of film or vinyl over the headlight to give it a different look, but sometimes it was even done on the stock sealed beam headlights! We saw mostly 7″ round headlights and many 5.25″ round headlights, but I don’t think anyone had rectangular headlights in attendance. It really goes to show how far headlight design has changed since the middle of the 20th century. If you need new headlights for your classic car, then look no further than Headlight Revolution. You can replace all of your sealed beam headlights, of any style with HID, halogen, or even new LED technology. Simply visit

Phase 7 LED Headlights by Truck-Lite

LED Headlights 27270C

The new 27270C LED Headlights from Truck-Lite!

They are finally here and ready to go into any vehicle with a 7″ round or 7×6″ Rectangular headlight! The Phase 7 LED headlight housings from Truck-Lite are dual beam (high/low), very bright (1,350 Lumens), and very efficient! They only draw 1.5 amps to operate and are about 1.5 times brighter than stock lights!

I gotta admit though, I personally liked the look of the old headlights better. The new ones look a little too “stock-ish” because they use a plain looking, albeit complicated design, reflector housing that two small LEDs shoot into to create the main light output. So even though the older style looked cooler, these new reflector LED lamps use less electricity and have a better light output. I did a review on a set of the older 7″ Round LED headlights and my only complaint was the beam pattern and output level. It seems that Truck-Lite has remedied both of these issues now though, here is a picture of the actual light output of the new Truck-Lite 7″ Round LED Headlight compared with a traditional halogen headlight:

The release of this new style of LED headlight is also the first time that any manufacturer other than JW Speaker has offered a 7×6 (AKA 200mm or 5×7″) LED Headlight. JW Speaker has had the market cornered in 5×7 LED headlights with their model #8900 dual beam product. The JW Speaker products are higher quality with better light output compared to the Truck-Lite product, but the pricing of the new Truck-Lite headlights cannot be beat. Truck-Lite LED Headlights come in at about half the cost of their JW Speaker, American made, counterparts.

For automotive enthusiasts who need these types of headlights for the cars and trucks that they need, it’s a win/win situation as more manufacturers experiment, and succeed, with LED forward-lighting technology. I’d like to get my hands on a set of these some time to do a formal review on, but I think anyone who chooses these new housings for their project will be very happy. They feature polycarbonate lenses, low power consumption, better light output than before and a cool “blacked-out” look.
