H4 LED Replacement

There are a few options that are truly good. I am fairly sure those you listed are NOT worth it, one clearly looks suspect. Beamtech's more expensive options are world class good, but generally sold in pairs. Note: The better H4 options use fans. Most do not work on AC without an additional rectifier, so certain older bikes (mostly dirt bikes) may need a rectifier to work properly.

Cyclops motorcycle headlights are also amazing. They have been doing this for quite some time and get it right.

Put another way, the configuration that works is fairly well understood. An educated consumer can tell what's going to work. LED placement, low beam cutoff shield (baffle) and fan.

These are excellent:

This is for a 2 pack but I like the extra small reflector as they describe to add to original reflector coverage. I don't know on Motorcycle, just daughters CRV. If I need to replace in future I'll probably try these Morimoto 2Stroke 4.0 LED

I have Nineo H4 LED in my daughters CRV currently. The bulb can twist so you maintain alignment. We have had no issue with getting flashed and much improved on overall. I still prefer my HID's overall in a slightly warmer temperature in bad weather and sometimes the reflection off signs.

Maybe not as much issue on a bike but I find the bright white LED's reflect more off the wet roads and glare in fog. Most LED's also don't create enough heat inside housing for snow/ice. Again probably not a bike concern.

This is compared to a Sylvania Sylverstar in her car. This was also 3 years ago so lots of improvements since then. These were listed 16000LM and have the fan on back for cooling.

In the motorcycle world the only h4 bulbs we use are piaa h4. Reason being is that they are very bright. And we have the liability of a light failing in a high vibration environment.
 
I replaced my PIAA 60/55 watt Xenon gas Super White bulbs that glow in the 4200
Kelin range with Speed Metal's 25 watt Cree LED H4 with a working high
and low beam...

Now you can look forward to piercing the darkness in style... you're

Any time you put an LED 'bulb' in a reflector housing intended for a regular filament bulb, you get light scatter, and blind oncoming traffic. Even the promotional pictures show light scatter into the oncoming lane. LED's placed on their mounting surface, simply don't emit light the same way. So a reflector housing will never direct the light from LED's correctly.

So many jackwagons running around with LED's installed in their old reflector housings, I feel like taking my handheld 1,000,000 candlepower Brinkmann spotlight with me on night drives, to blind them back. I won't, but I want to...

That's just not true.

There are LED bulbs that exactly mimic the size, position and shielding of the conventional wire filament. Some even offer the ability to rotate the bulb assembly to fine tune the cutoff. Beamtech has such offerings and will produce a cutoff so sharp, there is no scattered light outside of the proper beam pattern.

The LED is still mounted on a flat surface, so the light DOESN'T emit from it the same as it does from a glowing filament. Light scatter when used in a reflector housing is the result.

I've seen a bunch of LED lights installed into reflector housings, even ones that can be 'clocked', and I have yet to see one that works as it's claimed to.

The little shield they install on motorcycle specific (car specific bulbs too) does seem to help with this.

You can see it in the bulb I linked.

Your results may vary. Honestly, Id rather be as visible as possible.

2x. With mandated car DRL headlights our 2 wheel visibility has dropped dramatically. One reason many riders have installed additional front lighting.

Mercy 02... worse than jackwagons is the criminal act of blinding them back... thinking to take the law into your own hands, often with the goal of enforcing justice without legal authority is called vigilantism...

Mercy Larry... Read the last six words of my post, which you quoted...
 
California’s lighting laws are simple: "light cast from the front of your vehicle must be predominantly white to yellow. Any light cast from the back of your vehicle must be red."

Behold LED tail lights...

Hit the stop lights and now you're really shinning.. in fact the
intensity hurts the eye...

What did you put in there? My 29 years old Virago tail light plastic housing is fading so incandescent bulbs in there doesn't help.

Please Larry, practice your reading comprehension, and don't make false accusations...

Keep that in mind while you're out blinding other drivers with your hack install of LED bulbs into your reflector housings...

Its nice to see the mods (god awful moderators on this site btw) don't make it down to the motorcycle section of this forum.

I think its a valid point... We have all seen it where blinding lights from bikes are annoying. Honestly, most of the time during the day, I ride with the highbeam on anyways to be as visible as possible. Years ago (in California) my riding instructor actually advised us to do so. Bikes seem to get a pass with illumination unless no headlight which is the law.

To each their own but I see more annoying lifted HD trucks with purple LED headlight bulbs than I do motorcycles. But thats just me.

There are also other methods to create little shields like modifying copper pipes to fit over the bulbs with little to no glare. Heck my KTM has an LED Bulb in a standard housing from the factory.

Out back the twin tail light bulbs are replaced with dual round circuit
boards of LED... a generic plug and play system sourced at WSB Laguna Seca...
Adapting the LED to center inside the existing housing required some
mild fabrication but I don't mind the hours of work because it feels like
therapy tricking out my prized RC45...
