There's so much glare it projects the shape of the headlight housing, check it out!

 

What you see is the general problem with replacing a bulb with another where the location of the source of the light is in a different position.

As long as you do not drive at night, that's not a problem. But at night, you will likely dangerously pi$$ off the drivers in front of you. As other wrote about lights, too bright a front light might prevent the car drivers from seeing your turn signals.

That said, thanks for sharing the info, photos... That's nice, and the light is clearly "stronger", although 40W for LED seems quite high. That would be the equivalent of 150W halogen, something like that. So I would guess that either the light is not efficient, or the Chinese manufacturer is quoting the total for 2 bulbs? The last option is that your light is really equivalent of 150W halogen lights (roughly 3 times what you had before).

 

I have the cbr300r and yesterday I decided to switch my headlights to the led bulb as well.
the only problem was the base of the bulb was huge and the rubber gasket for the housing and that spring clip just barely went back on to hold the new bulb in. now I need to figure out a way to secure the wires hanging out and keep the housing from getting moisture in it...

 

I do agree 40watts for a LED bulb is quite high. Does it have little Chip LED's on each bulb? How many? I thought LED's didn't get that hot? Have you felt the heat sink after having the light on for a bit? Just wondering if the heat sink gets real hot if the rubber seal over it can withstand the heat

 

Completely forgot to mention there's a fan at the back of the heatsink and it's always on and kinda loud.

 

The light is very bright, way brighter than the stock headlight. Similar to putting an HID in regular housing, the cutoff is nonexistent. Aka very bad. The lowbeam LED outputs a similar amount of light to the stock halogen on High.

I did a bit of reading up on other people's experiences with replacing halogens with LEDs earlier so I managed to find one that has the LED emitters located in about the same places as the filaments of a halogen, and include the little reflector cups under the front emitters too. This is for my wife's CB300FA which uses a single H4 headlight.

I actually purchased two pairs of these headlights since we have a few bikes to put these into, I already did a brief writeup at another bike forum but here are the pictures for the CB300FA. Each pair was about USD$30 shipped, so the price was right.

First picture shows the bulbs we purchased. Box says 8000 lumens for the pair so it should be 4000 lumens each. I'm guessing these are Chinese lumens but the bulb is no doubt brighter than the stock halogen. Based on the product code, I'm guessing these bulbs run 25W, but I don't know if that is for the pair or for each bulb.

Next two are the stock halogen low and high beams.

The two after that are the LED low and high beams. The beam patterns and cutoffs are fairly similar by my eye, but I had my camera flash on which produced some artifacts with the capture. The LED is definitely brighter than the stock halogen, and much more white.

Next two are a close-up of the installed LED, and a shot of the bike with the electricals on. Looks good. Next I just need a LED flasher relay and some replacement LED bulbs for those indicators... are they BAUS15 sockets?

 

I'm replying to this post to 'bump' it to the top as it got lost in the approval required issue we had recently.

 

That looks good. Cut off appears to be close to stock. Could you take a photo in the dark, also at a wall?

 

I'll see what I can do, will probably have to wait until Saturday night. I park in a lit underground parkade so I need to find a suitable wall somewhere dark...

 

Thanks for that! It looks very good, some additional glare but not a whole lot.
