SEALIGHT 9005/HB3 9006/HB4 Bulbs Combo, Super Bright Bulb, Plug and Play, Fanless Light, Non-Polarity, Fog Bulbs, Powersports Accessory Lights, Pack of 4

The SEALIGHT H4/9003/HB2 Bulbs were easy to install with no need for extra parts or harnesses. They worked perfectly on the first try and provide a bright, clear white light. Excellent quality and brightness for improved visibility.

Picture shows new bulbs on the left and older halogens on the right. Huge improvement. A ten minute job and you’re done. Very easy to install. Comes with detailed instructions, two sided tape and zip ties if needed for the small ballast boxes, and extra “O” rings for the bulbs. Highly recommend.

These are incredible. My 4th set across 4 cars. Won't ever need to waste money again on frequent/expensive/less bright stock halogen bulbs again.

I put these into our 2007 Jeep Grand Cherokee that had its original bulbs. Boy, what a difference.I do have an issue with 1 bulb that will not work on either side, so I do have a message sent to Sealight Customer Support. I'm just waiting to hear back from them. If not for that I would have given 5 stars.

These were a direct fit for my high and low beam bulbs on my 2001 Monte Carlo SS. The daytime running light feature doesn't work since the DRL's use the high beam bulbs with a pulse width modulated input for reduced output from the OEM halogen bulbs and the power supply isn't powerful enough to illuminate the LED's in the DRL reduced power output mode but work fine when switched on and I'm not getting a "bulb out" message when using them. The bulbs themselves have a little module about a quarter inch thick and slightly smaller than a credit card inline with the wiring between bulb and connector. For my car the bulb connectors were inside the housing but the LED bulb wiring and module fit fine inside the headlamp housing for proper reinstallation of the bulb access weather seal cover.

I would definitely recommend these. They fit well and look nice. They have helped my dark morning commute nicely. I've had them on for a couple weeks and there has been no flickering. They come with their own ballaster which is helpful.

(FOR OTHER BUYERS WHO NOTICED THE SEALIGHT S1 "HIGH BEAMS" aren't very bright, this is why)Last night my installer (a Toyota dealer technician) spent hours trying to install a SEALIGHT S1 H4/9003/HB2 LED headlight upgrade kit in a 2007 Toyota Prius (originally equipped with conventional incandescent headlight bulbs). Attached photos help illustrate these two problems (using the same terminology as in the installation instructions):1. The "shank" of the "lamp body" is too short. At first he thought it was not possible to compress the OEM rubber boot enough to get the tabs on the "lamp body" to engage the twist-lock slots on the "socket," but testing the fit on a bench showed that he if pushed straight down with all his body weight, the tabs on the "lamp body" would JUST BARELY engage the twist-lock slots. However, when installed in the vehicle, it is practically impossible to apply that much force. In a Prius, the installer must choose between rigging up some type of lever to pry forward with WAY too much force, or having to trim off the back of the OEM rubber boot.2. The bigger problem is: the HIGH beam LEDs do NOT turn on when installed in the vehicle when the headlight control switch is in the HIGH beam position. Instead, the HIGH beam LEDs only flicker for a split second and the LOW beam LEDs turn on, meaning that there is NO difference in illumination between the LOW beam and HIGH beam regardless of the headlight control switch setting.After discovering this problem, we expended more time bench-testing the SEALIGHT S1 H4/9003/HB2 LED Headlight Bulbs. Applying 12vDC to either the LOW beam terminal or the HIGH beam terminal caused the LOW beam LEDs or the HIGH beam LEDs (respectively) to turn on as expected. We then tested a conventional incandescent headlight bulb in the vehicle, and found that also worked as expected. We also tested the voltage on each terminal of the headlight power connector, and found that 12.x vDC is present on EITHER the LOW beam terminal OR the HIGH beam terminal, when the headlight control switch is set to LOW beam or HIGH beam (respectively).This problem is present on *BOTH* of the S1 LED headlights I got, which makes it pretty clear this is a design flaw, not a random defect, and it probably affects a LOT of other vehicles. This would explain why so many other reviewers comment that the SEALIGHT S1 high beams aren't very bright... because the high beams are NOT actually turning on.I ran other tests which lead me to believe that the source this design flaw is in the "driver," which causes 12vDC power from the HIGH beam electrical connection to be sent to the LOW beam LEDs. This explains why the SEALIGHT S1 works if 12vDC is applied in a bench test (when there is nothing connected to the unused terminal), but not when they are installed in a vehicle (when all three wires are connected all the time).Long story short: In a 2007 Toyota Prius that functions normally with OEM-style incandescent headlight bulbs, the SEALIGHT S1 H4/9003 LED upgrade kit DOES NOT function properly, resulting in LOW beam only, even if the operator turns on the high beams.

My 2003 Silverado looks even more awesome now! These LED lights are very bright and the halogen bulbs don't even come close. The 9006 & 9005 lights fit great, albeit I added an extra rubber seal (several included) to make them fit very snug. These are well made and the built in resistor does not hamper the install...which only took a few minutes. There is NO hyperflashing!!!! Everything works great. All lights on the front are now LED complete...including this same brand as fog lights. Everything functions properly. After a lot of research, I'm glad I chose THIS brand. I'll add pictures at a later time once the weather clears.
