Osram H4 46204Cw LED Retrofit 12V (Pack of 2) White

The media could not be loaded. *Build quality :-Top notch...As we can expect from a reputed brand like OSRAM. Price is high. But still its a value for money product.* Comparison :- Night-eye or Novsight are brighter(as they consume more wattage) than OSRAM. But OSRAM is more sorted, No unnecessary brightness, no blindness for the oncoming traffic.* My experience :- I'm using it on my Hero Motocorp Ignitor (which comes with a 30-35w,12v halogen lamp for which I've faced problems while night riding). Previously I have used other LED lamps too. But there is no comparison with OSRAM LEDriving HL Premium H4 lamp. Though reflector of my motorcycle is a halogen set-up still its low beam spread is just awesome. High beam is also great. Everything is sorted and no blindness for the oncoming traffic.* About connection :- you have to fit it on a DC connection. Connecting with a AC connection is just not a good idea.* Verdict :- If budget is not a concern for you then just go for it without any hesitation.

The media could not be loaded. I bought these for my Honda City Ivtec 2010, socket type H4.- I was previously using 100/90 osram halogens with a relay wiring kit, however they were still not good.- Then I upgraded to 130/100 Phillips Halogens, though had the best visibility, it gets hot as hell, they also turn the headlight transparent cover to pale yellow due to heat2 months Later the high beams were fused------------------------I bought these H4 LED's in prime day sale, thanks to amazon , got it at near cheap 3200 rs.Pros:1) Great brightness with increased coverage on the sides than stock halogensAlso, my car do not have fog lamps.2) As you see in the video In total dark roads, it's the king in its segment hands down. Overshadowing these days projectors at ease.3) you'll get the best in class quality materials on this, German made so no questions there, has 1 yr warranty.4) It's great on battery (25 watts , half than stock what company gives), even you can use them on fog lamps if you have.5) Doesn't heat at all, very cool , 6000k bright white light spread ( not tinted blue)6) the focus of the filament is sharp , crisp ( make sure to install lamps in vertical position)Also due to LED's the high/ low , dipper beam switching is crazy fast.7) Direct plug and play in the socket type of your car ( so you need to remove the Metal plate from bulb first, install the plate only on your car , clip it, then install the rubber seal , at the end install the LED's slowly, making sure nothing is blocking the led fans )8) It's not illegal , as it's within recommended wattageNow the cons -1) 5/10 points on rains, foggy weather - not sure about fog, it's yet to test, but on rains, the roads are not that visible, more over the light scatters.Hard to see distant object in total heavy rains,You need to have a fog lamp to overcome this, but running these on rains / fog is not at all a good idea, as the light is white, visibility is poor there.2) Due to higher Kelvin , the oncoming traffic will suffer due to high beam, use low mostly.3) the light range is good in city ,however not that good for highways, not a good range there.4) Slightly overpriced, it should be near to 2500 , however if you are getting these below 3500 , still a good dealOVERALL I WOULD GIVE 7/10In case you donot have monsoons ,winters then it's 9/10.Hope this helps :)

I installed this in an Alto 800 that comes with phoenix 60/55w yellow light halogen bulb. I wanted cool temperature light and brighter. In the beginning I was skeptical about this because it is “just” 25w. Read many reviews and decided to give it a try.Pros :1. Definitely brighter light.2. Good throw.3. Cool daylight.4. Doesn’t hit very high and blind opposite side vehicle.5. The headlight glass does not get hot at all.Need to keep in mind :1. Not such a straightforward installation but not very difficult either. Note that there is no need to cut the headlight boot cover rubber and all.2. Need to tie the cable to some other cable to prevent unnecessary rattling noise and prevent cable from touching some hot engine parts.3. The orientation if not done correctly light focus will be pretty bad.4. Too early to comment on longevity but considering that there is almost no heat generated longevity prospects are promising.Cons:The only real con I can think of is cost. Even though is is a branded item and not a Chinese reverse engineered product, considering that many people are upgrading to LED and many cars are coming with stock LEDs this should have been cheaper. This higher cost makes it not worthwhile to buy and keep spare bulbs of the same kind like how we would with halogen.

One bulb stopped working just 1 day out of warranty , and service warranty process is quite tedious

This one is the best for any bikes with 35/35w headlight.Pros:1. Perfect beam pattern, clear separation between high and low beams on my Pulsar 150.2. Brightness: much better than stock. Also better than all of the bikes with 55w halogen headlights. Don’t ask about those bikes with stock LED headlights ;).3. Color temperature: perfect. Not too blue like those Chinese leds.4. Build quality: top notch.5. Only 25w. No harm to the bikes electrical system. No overheating.6. Not too expensive. Can’t get better once at this price point form any other reputable brands.Cons:We need to cut the dust cap to install this. This is not actually a cons for this product. You have to do this if you are trying to install any other led/hid lights.Note: It’s better to install it yourself if you are confident. You can perfectly align the light and fix the driver properly so that it won’t move around while driving. Otherwise go to a trustworthy mechanic.

Writting this review after using this in all the conditions.Pros- material quality is superb. , Easy to install.Cons- brightness is not that effective on highways and in city as well. Other lights overshadowed our light and visibility is very less. I think 25 wt is not that effective. I have installed this in Honda Amaze without a projector head lamp.Advice - use this with projector to improve brightness.
