Product Details

GTR Lighting H4 CSP Mini Series: The H4 CSP Mini from GTR Lighting is a fantastic gateway into LED Fog Lighting Upgrades. At only 16w it draws roughly a third less power and is twice as bright as many OEM Bulbs. The design is especially impressive with a copper PCB and Z ES Chips that are perfectly aligned to emulate the filament they're replacing. You'll get 2500 lumens and a shockproof, waterproof lighting upgrade that will last for years.

Fitment: Perhaps one of the things we love most about the CSP is its small stature. Thanks to that low power draw it doesn't require the complex heat sinks you see on other lights. The compact heatsink is more than adequate and that allows the bulb to fit just as easily as the original bulb did.

Adequete +: When we say that this thing evacuates heat adequately we mean it. It's been tested at a temperature of 194 degrees for 15 days straight without failure. You could live on Mars and this LED bulb would function just fine.

Keeping Cool: Part of that successful heat evacuation is due to an integrated heatsink that's built from the highest quality aircraft-grade aluminum. That provides them the ability to shed heat more quickly than any other option without needing a fan. So you won't get any noise either.

Great but not the greatest


I got these in April this year (2020) and I really liked them and it lit up the road much better than the halogens, but now I’m having an issue with one of the bulbs, the LED chips on on side(left) of the bulb tends to cut out, I was hoping it have any issues for at least 2 years.

Looks better than stock. I

Looks better than stock. I like the white, daylight color. Easy enough to install. Fit was practically perfect and this was in my tiny Ducati headlamp that has basically no wiggle room for any play. My only complaint is that I only needed one seeing as how it was for my bike.

Best headlights for a tight fit, hands down!

Eric Pyne  

I needed to replace a headlight in my 2006 Yamaha FJR1300ABS for inspection, and thought i would finally upgrade the factory yellow halogens. While the process was long and tedious, the results are incredible. Beam pattern is perfect, brightness is easily 200X better than stock, and the requirement of less voltage makes everything else on the bike run smoother(signals, dash screen, etc.). I run these bulbs in my 2018 F150 also, and have nothing but great things to say!

Great LED bulb for older motorcycles

Comet Brower  

I have a 1994 Honda CB1000 with an H4 bulb in an enclosure that looks like a 7 inch round sealed beam. I have wanted upgraded lighting for it for many years but the only real option I had was an "upgraded" halogen bulb which made a little difference but not what I was looking for. I have installed GTR lighting bulbs from Headlight Revolution in my SUV and Yamaha FJR1300 and it was clear neither of those option would come close to fitting the CB1000. I came across the GTR Lighting CSP Mini LED H4 Bulbs and they looked like they "might" fit. The bulb arrived well packaged so I gave it a good look over before I tried to install it and was a little worried as it was 3/8 of an inch longer than the bulb I wanted to replace. I gave it a go. The bulb installed perfectly but the entire lens would not quite seat back into the rear cover as it was maybe 1/16 of an inch too long. I pulled it out and moved some wiring and it was closer but I would have had to put quite a bit of pressure on it to install the screws. when I took it back out two inspect I noticed the plug from the bike the the bulb was not seated flush (off by 1/8 inch). So I got out my Dremel and removed a little less than 1/8 of and inch from the prongs on the back of the GTR Lighting CSP Mini LED H4 Bulbs. It fit perfectly! The bulb is many times brighter than the "upgraded PIAA" halogen bulb it replaced and the cut off line is even sharper. I am very pleased with the results and would recommend the GTR Lighting CSP Mini LED H4 Bulbs to anyone looking to upgrade the lighting on an older motorycle.

The best I've ever used

Jason Babila  

I have been in search for a pair of H4/9003 LED lamps for quite some time to replace the halogens, I learned about Headlight Revolution via YouTube about three months ago and learned about different types and styles of LED bulbs, I managed to find what I needed and these LED bulbs are by far better than the halogens I've been using, it's so much clearer and crisp, it makes it much easier to see the yellow and fog lines in total darkness and poor visibility conditions, great top cut off and no one has flashed their high beams at me yet.

Great replacement bulbs with no modification...

Joseph Freeman  

Replaced the stock halogen headlights in my 2013 Tacoma with these. Relatively easy to install, but was much easier after moving the battery on the driver side and washer fluid reservoir on the passenger side. May not have to do this if one has very small hands (like, maybe a 5 year old's), but no other issues. Very nice output once clocked correctly. Not the brightest LEDs available, but way better than stock, built very well, and gives a much more modern appearance.
