9007 HB5 Led Headlight Bulbs Hi Lo Beams 100W 12000LM 6000K Brightest White ZES Chips Light Conversion Kits

My car (a 2011 Mercedes-Benz SL550) uses projector lens bi-xenon HID bulbs for both low and high beams, but it also has a pair of reflector lenses with halogen bulbs used for the "flash" feature, and for fill-in when the bi-Xenons are in high-beam mode. I recently replaced my worn out bi-Xenon HID bulbs with new ones that have a 6000K color. That brighter, whiter light made the halogen fill-in bulbs look very yellow, so I went in search of a solution and found these LED bulbs. Since they are just used for flash and fill-in, I was not too concerned with beam pattern or output. My biggest concern was fit and compatibility with my car's bulb monitoring system (often called a "CAN-bus" system). These bulbs promised "plug -and-play" installation, no errors, excellent light output, the ability to focus the beam pattern.PLUG AND PLAY: On my car, this was not the case. Most H7 bulb mounts have a simple wire clip holding them in place that should easily fit over these LED bulbs, but my car uses a complex metal "carrier" designed to snap over the back of the bulb and then twist-lock into the headlight housing. Since these LED bulbs have a large heat sink and fan unit on the back, this carrier would not fit over that. Fortunately, the retainer ring on these bulbs is removable to supports their focus feature. I removed that and used a Dremel tool on my car's bulb carrier to enlarge its opening so it would slide over the front of the bulb, then I replaced the retaining ring. I don't necessarily fault the manufacturer of these bulbs for this issue since most H7bulbs housings use a simple wire clip. I suggest checking your car's housing before assuming it will be plug-and-play. The wiring connector was a simple plug-in which fit securely, and my headlight housing has plenty of room to accommodate the large heat sink and fan housing on the bulb.NO ERRORS: The bulbs work just fine and I get no bulb errors. Standard H7 halogen bulbs draw 55w each, and I believe these LEDs are rated at 50w each. There is a small plastic box on the wiring lead that may be a resistor to increase current draw and avoid errors.LIGHT OUTPUT and FOCUS: Since I am just using these bulbs for flash and fill-in, I am not really concerned about light output. Just to test them, I switched off the main bi-Xenon headlights and the held the stalk in the "flash" position. I think if I were using these bulbs as my sole lighting source, they would be disappointing. Their light may be brighter and whiter than halogen bulbs, but it's not very uniform or "full". There are dark spots in the beam pattern and the further the light travels, the more it looks "foggy". This isn't really a defect in the bulbs, but just the way LED bulbs retrofitted to a halogen reflector housing will perform. Factory LED headlights use specifically-designed lenses to properly project the light. I did try the focus feature which involves twisting and adjusting the depth of the the bulb, but it made no real difference.Overall, I am happy with these bulbs, but I am not sure I would recommend them as a primary light source in a reflector housing. I would suggest replacing just one and then comparing it to the other stock halogen to see if the LED gives adequate illumination for safe driving.

Udate: I have since learned that the reason these bulbs are able to light up signs on the right side is that they are not for the US market. These bulbs have the cutoff pattern for the EU market. As such, they are illegal to use in the US and will not pass inspection. I've attached a diagram showing the legal cutoff patterns in different areas.I absolutely love these LED headlight bulbs. They are very bright and were an easy to install direct replacement for my halogen GE Nighthawk 9003 bulbs. They at least seem brighter, but it may be the 6000K color. They seem to light up signs much better than halogen bulbs. Even with the wiring and the attached box, they was enough room in my housing to completely insert the wiring and put the dust cap back on. I don't know how much air movement there will be, so the fan may not be as effective as it would've been had I left the dust caps off. Only time will tell by how long these last.I don't like the fact that they are 360 degree adjustable. They should have stops to adjust only adjust the cutoff slightly to the right or left. It's too easy to end up reversing the cutoff and blinding oncoming drivers or, if not careful, you may end up reversing the High/Low beam direction.

Had these lights in my last motorcycle loved them. I put them in my new 2017 zx10r and it was a tight fit but everything worked and went in smoothly. Very happy with these lights will be getting them again at some point.

Good

Nice

These are listed as CANBUS. They flicker back ond forth,left light then right light, like a disco ball when the car starts and the light switch is off. When they are switched on, they are very bright, but it makes the "Bulb out" error come on the screen.I'll have to return these and try a different brand. I was going to order more for the fog lights. But the flickering and warning lights are annoying and I can't drive during the day with the lights off if they are going to be flashing like a police car.Any help from the seller is appreciated.2013 Mini Copper Roadster

In my D650 dualsport motorcycle I replaced a two year old LED bulb that was even dimmer that the OEM halogen. I had continued to use it though because the color of the light got noticed by other motorists better. This new bulb is simple fantastic! Low beam is four times brighter than the highbeam of the old light. High beam would probably be safe for 100mph. In the OEM Suzuki light housing, the low beam cutoff is perfect so there is no blinding of oncoming drivers. An amazing amount of light from a single small headlight!

It is not what the publication offers, it is a low quality product, it looks like a disco ball, rays of lights everywhere.
