KOYOSO H4 LED Headlight Bulbs, 10000LM Car Motorcycle Headlamp Front Light Bulbs, Direct Halogen Replacement, Xenon White 6000K 12V, 2 Lamps

I installed the said LED on my Land Rover Discovery 3 and I'm delighted with the results. It really adds to the vehicle.It took a bit of an effort to get the bulb to clip in but I eventually succeeded. This involved maneuvering the clip around the bulb between the bulb fan and LED before fully pushing down the bulb to clip in place.You can also choose to not to fully clip in the bulb into place but just get it snug in the socket and manoeuvre the clip to have resistance. That works perfectly too and it's much easier to install.In terms of brightness, it is significantly brighter than the traditional bulb. On the right in the photo you will see a high quality traditional bulb and on the left is the LED bulb. The photo does not really capture the increased luminosity of the LED bulb.Overall, I'm very impressed with the quality of the cool light emitting and also the cost which is very good value.

Lights look great and really easy to fit. The collar comes off the bulb which makes them much easier to fit as you don't need to push the fan bit through the cage etc.These were bought to replace older LED bulbs that I had. The built quality is excellent as these are metal rather than plastic. They are also much brighter than the bulbs I had before. The fan is a great idea as the old ones had the metallic ribbon - the fan keeps them cool.Would recommend these as they are a bargain for the price

Aas I want to replace the old bulbs to LED one and shopping around then found this one and turned up to be very good. The package looks and feel posh, and the light bulbs look well made, the initial installation did not work then quickly realised the positive (+)and negative(-) label on the light bulb socket labeling the wrong way, as I believe my car's label, so I inserted the LED socket into the other way round, then the bulb light up straightway. It is very bright (6000k) and hoping will last for a while (only time can tell). I would recommend it car owners (for Toyota) want to try LED headlights.

**Update 4 Mar 2019**So after 5 months approx of use these are still working fine and have improved night vision drastically.They have now been tweaked to get a pretty good beam pattern however as stated earlier I don't think they will pass an MOT test.Overall though I am extermely pleased with them and can recommend them if you have the time to fiddle with the alignment.Can't give a 5 star review of the product as it did not work as the original when initially fitted however after some tweaking I have now got better vision at night than the crappy standard headlamps.The bulbs were fitted to a Triumph Tiger Explorer of 2013 vintage and as any owner, UK owner at least, knows, these have the rubbish 'Euro style' dip beam which means just flat (I was under the impression that the UK construction and use regulations specified that the headlamp MUST have a kick up the nearside but maybe that was an older version) and bloody poor. It's like riding into a black hole at night on anything bar a good wide dual carriageway.Fitted these and immediately MUCH brighter, not HID stupid blinding bright, but far far better than the original bulbs.When fitted these had a 'U' shaped dip beam pattern which is not good for oncoming vehicles at all (and I got flashed a couople of times before I adjusted them), hence the 4 rather than 5 star review.However with a little tweaking of the position which you can do I was able to get a beam pattern with a good kick up the nearside (actually a little bit too steep but so what) and no blinding.High/main beam is truly amazing now!I used to hate riding to work in the winter no beacause of the cold but beacuse its dark both ways but not anymore, now I actually find the longer country routes home now as the headlamps are that much better!I would actually go so far as to say the headlamnps on the bike are now actually better than my car ones!Be warned though the fitting is actually a bit of a fiddle but they do go in. Don't try fitting the adaptor ring to the bulb first as I did as you can't, fit the ring into the back of the holder first, the connect up and feed the cable into the back of the headlamp shell then push the bulb in place and twist to position. At least this is what I had to do on my bike, others may be different.Only had them fitted for a couple of days so far so I cannot comment on longevity.I am actually so impressed I may very well get some H7's for my other bike.I don't think they will pass the UK MOT test however as the dip beam, although with the extra scatter you get is far better for night riding, will I think cause the fail (I am not going to have my usual rant about stupid MOT rules although I did think about it :) )If you have rubbish headlamps and are prepared to spend some time fettling the settings I would give these a go.I will add that I had the adaptor rings missing intially but after contacting the seller and after some initial confusion as to what was actually missig, they sent me out some really quickly and with no quibbling so a 5 star review for the seller anyway.Chris B

Got these today and fitted them in my BMW E81 116D 60 plate, they are relatively easy to install, the removable plate that goes in first is somewhat ingenious. They fit in the headlight enclosure and the large fan part of the bulb fits well even behind the cover plate of the headlight enclosure. Took 5 minutes, plus the bulb icon on the dash is no longer showing, they seem bright but it is daytime so can’t comment on actual brightness or how long they’ll last. Will update if any goes wrong in future.

Easy to fit and smaller than some other bulbs I have used in the past.These ones have an in-line unit which needs routed somewhere out of the road but wasn't a hassle.Initially I had thought these were realy good. The beam pattern looked the same against a wall and they appeared bright enough. Trying them once in the dark showed me how wrong I was. The light on the road was less than the halogen bulb. Mine are HB3 projectors and the low beam is terrible. The Main beam is fantastic but it doesn't make up for the poor low beam. These may be ok with reflector headlights. The other concern I have is that HB3 should be rated at 60w and these are rated at 50w.

Pros:- Small/compact;- Quiet fan;- Looks really bright;Cons:- Cooling is not quite efficient. Area around LEDs gets very hot, while radiator is lightly warmed. For sure this will shorten LED life.- Fan is not "turbo" fan, unless its name is "Turbo FAN". Speed is slow and maybe this leads to previous point.- Dust Cap Housing is too loose for H1 LEDs, don't know about others. There is a gap of relatively 2mm.Overall: 4.5 stars or something, in other words - not completely satisfied by the purchase.Revised score after testing 2.5.
