Comparing Aux LED lights

If you have ever ridden a motorcycle in an area without street lights at night you know how much having one head light sucks. For this reason I decided to install aux lighting on my bike.

A while back I purchased a pair of aux LED driving lights online. This design is available from most online stores like Amazon, Ebay, AliExpress, etc. and the price is fantastically cheap. The issue was when they arrived. The bar clamp design prevented me from installing these on my Denali light mounts and they were about as bright as a flashlight which is to say none too bright for auxiliary driving headlights.



I subsequently purchased these (see below) and just took delivery. Despite being physically smaller and sightly lighter than the original LED lights I ordered they manage to be much brighter. Holy crap are they bright. They light up a dimly lit room like a UFO just landed outside the window. The beam is much wider but they also project a high intensity narrow focused distance beam as well. Can't wait to get these mounted. For now I just have the one but it is much brighter than a pair of the others. Supposedly projects 4000 lumens. Note I don't think these things actually draw 40 watts as that would be ridiculously high for an LED light and they power up fine from my trickle charger that does not supply 40 watts. I am powering this direct from the battery but via a $2 relay that is switched on and off by the high beam.

That top set looks entirely like something that clamps to the fore end rail of an AR15. Might be(?)
Slightly off-topic, but timely, I just snagged a pair of PIAA H4/9003 LED bulbs for half-whack. When I develop enough energy to pull the fairing, I'm going to plug one in and play.

Have a look at www.delourmel-moto.fr for EX belly pans with holes for auxiliary lights. You need to follow Kawasaki then GPZ 500 to see what they do for our bike.

The light contain 4 reflectors, one for each LED. I suspect the reflectors are all tuned differently as you get great distance projection but also a wide beam flood of light in front of the bike. Not great for oncoming traffic but great to see everything. I run these off the high beam so they are only on with the high beam. Only having one for now is a big improvement but I have a second one on order, not sure I need it now.

The light unit seems to get quite hot when running which would imply these are drawing extra power that gets converted to heat and thus are less efficient than lower power LEDs that run cool. There are cooling fins on the back of the aluminum cast case to dissipate this heat. I worried the single bolt mount would slip but it seems to lock up when you tighten the cross screw. Overall very happy with the addition.

Used a cheap relay ($2) from AliExpress to power these direct from the battery, the relay is switched from the high beam. Also purchased some cheap plugs from the same source so I can unplug and remove the lights when removing the fairing. I don't think you would want to run these with your low beam headlight since they would blind oncoming traffic.

Interestingly I noticed the volt meter on the bike jumps up 0.1 to 0.2 volts when I engage the high beam switch now. Did not notice what it was doing before the light install. Probably a factor of how the voltage regulator on the bike works, I had expected a voltage drop not a voltage rise with the increased load.

I mounted it on my Versys using aftermarket mounts I purchased used, they're made specifically for the bike however I suspect these could be easily through bolted on the Kawasaki 500 fairing with some washers on the back side or the crafty could fab a mount. You can also buy generic cheap fork mounts that clamp around the upper forks on AliExpress. As far as I am aware no aftermarket supplier currently makes custom fit light mounts for the 500.

PIAA uses a tiny laptop-style cooling fan mounted on the rear of their LED bulbs. That adds a bit to power consumption, but I have not put a meter on them yet. Your lights give great foreground visibility. How are they on long range, or can they be adjusted to illuminate farther out?
