Gerhannery H4 LED Headlight Bulbs Conversion Kits for Car Replacement, 72W 6000K 8000LM 12V Super Bright Car Exterior White Canbus Headlamp COB Chips Light Bulb Replace 2 PCS/ Set (H4)

These are Crazy Bright! I will never buy halogen headlights again!I bought some brand new osram halogen 'night breaker' lights a month ago, they were whiter than my stock Citroën c1 lights but not that much brighter.However these! Are the TRUE UPGRADE. they are so bright! (in fact I wonder whether it will pass mot due to the fact they're so bright). It almost looks like my stock lights are constantly on full beam.Beam pattern is even and sharp. Lights go very far as well now. Perfect for being on those motorways which don't have any street lighting at all!I have them installed in my 2007 Citroën c1. I Dnt have a projector so there is alot of scatter - however the beam is still pretty concentrated in terms of it lighting up the area in front of the car :)Very pleased with them.I will update this feedback if anything changes.

I have used this to upgrade my HS1 bulbs on Honda Forza300 Scooter.First impression when you see the box is very good. It comes nicely packed. But when you pick the bulb up you see that quality is average, but for the price you cannot complain.Fitting it to scooter was the pain. Round bit of the bulb (collar) is not attached onto the bulb. You have to slide it and twist it. Now the ring locks in place only thanks to two, plastic grooves. Trouble is that headlight dust cap (rubber, round cover) must be fitted between bulb and the collar ring. So you are trying to fit bulb, with massive rubber dust seal, and with all that you have to try to secure metal spring holding bulb in place in the headlight housing. That took me good 20 minutes at least. Once fitted, I realized that because I was wiggling this for long time trying to fit, one of two plastic grooves on the ring became loose. This causing bulb not sitting straight and light beam is going too high up. not much, but still.Is is brighter - oh yes it is! Especially when comparing to HS1 bulb which is 35W. It is so bright, that your eyes may pop if you stare on it for to long :)I would recommend it and it is good value for money. I'm sure that if I would not have trouble fitting it all would be perfect. Time will tell how long it will last forUPDATE SEPTEMBER 2017:OK, bit of update. Although product is well made and very bright, issue is that this bulb does not produce correct light pattern. It turns headlight into floodlight sending strong, bright beam all over the place, not under the horizontal line. This is causing plenty inconvenience to other road users who are switching fog light or flashing headlights thinking I'm riding on high beam. I though it will be OK but as it is getting darker this is causing more issues. For me, it is back to standard H4 and this kit lands on the shelf.*** In my option, this product will cause your headlight to produce incorrect beam pattern, will cause MOT to fail and is illegal ***

I wanted to love these so much but it isnt happening i'm afraid. The colour is great and they are bright too. Unfortunately the beam pattern isnt very accurate in normal (i.e. not projector) headlamps... it bleeds too much light so they are dazzling to oncoming cars. Also the high beam isnt that different to the low beam, just brighter. So i'm going back to the Philips X-treme 130%+ halogens which have a terrible lifespan but a good accurate beam.You can see in the attached photo the difference between the Philips 130%+ in the offside (drivers side) headlight, and the LED in the nearside.

Third attempt to find LEDs which worked with my car, product was easy to fit, with it's separate 'collar' it is easily reversible to get the correct high-low beam without the need to re-wire the three-way socket. Fitted in minutes, like fitting a replacement bulb, only time wasted was getting the headlamp units on my Polo 6R out.Previous LEDs did not form correct pattern for MOT headlamp alignment and necessitated the removal of the headlamp bulb guard to attach the whole bulb and trying to then screw in place a tiny screw which held the spring mechanism. Light output of previous LEDs was poor too, with yellow fuzzy edges.Very pleased with new Gerhannery replacement LEDs, nice bright light, good field of coverage, no yellow fuzzy edges, easy to fit, and do not cause any Canbus dash warning errors (to a Polo 6R anyway). An excellent buy for me ...

Works well. Nice color light. I have installed onto my motorbike took few minutes. Must say that it's not as bright as I expected but is still quite bright. Now the high beam doesn't really function as halogen does because led light disperses much more but I feel more confident with this bright bulb on my motorbike. I feel like everyone sees me coming.

Not bad. Far brighter than my old halogens. However they don't give a very sharp cutoff. Maybe someone will share with me the secret to getting a better beam pattern from these bulbs?I do think the pattern depends entirely on the shape of your headlamp housings and these may work better on some vehicles than others.

There is no upper cut off point so impossible for me to have used it on the road. I don't know if its due to the housing my car provides. It is bright and hence the 3 stars.

Nice but not sure if it will catch on fire. I did as instructed opened the copper and covered it with the rubber casing. But will this be safe? Other than that the brightness is perfect
