ExNotes Long Term Test: Oxilam LED Headlight Bulb

By Joe Gresh

As you’ll recall from the Oxilam headlight review we published on ExhaustNotes a while back, I loved the thing. It gave a much brighter view at night and the light source was positioned in the correct spot for the reflector on the ZRX1100 Lawsonsaki. Low beam was wide and had a sharp cutoff so as to not blind oncoming drivers, and high beam lit up the dark New Mexico roads nicely.

Unfortunately. the bulb burned out on my bike after only 3000 miles. Considering the original halogen bulb lasted 35,000 miles, 24 years, and was still going strong, I was disappointed.

Taking the bulb apart revealed a neatly constructed circuit board, a cooling fan, heat transferring grease to the large aluminum heat sink, and broken solder connections at the main board/plug connector junction.

The board connections are tiny and I may try to re-solder the connections (there are four of them broken: two on either side of the circuit board) but I don’t hold out much hope.

The Oxilam kit came with two bulbs, and I’ll pop the other one in to see if my failure was just a fluke. I do like the quantity of light produced and riding with a plain old halogen seems dark now.

My new, revised rating on the Oxilam LED headlights is: Don’t buy them just yet. Wait until the second Oxilam has proved itself for 24 years. I’ll be sure to report back here if I’m still alive.

ExNotes Review: Oxilam LED H4 Headlight Bulb

By Joe Gresh

The Carrizozo Mudchuckers and I took a spin over to Jerome, Arizona last week. The trip was around 1200 miles all in and we ran late getting home, which meant I had to ride 100 miles in the dark. Normally I avoid night riding because most of my motorcycles have terrible headlights and my night vision was dim before I had both my cataracts replaced with new lenses. Plus, at night you can’t see anything except the road ahead.  It’s pretty boring.

For the Jerome trip I was riding the Kawasaki ZRX1100; that bike has the best headlight out of every motorcycle I own. To my surprise the night ride was not as bad as I thought. I could see fairly well and made it home without running into an elk. Which got me thinking about the shorter days of fall and the fact that I sort of enjoyed that 100 miles of darkness. Could I improve on the acceptable Kawasaki headlight?

Enter the Oxilam LED H4 bulbs I purchased on sale from Amazon at $39, shipping included. They are a tad pricey but you do get two of them. Oxilam’s ad copy makes wild claims about 500% brighter and 10,000-hour life span. I can’t speak to the lifespan but the bulb sure doesn’t look 500% brighter.

The Oxilam came securely packaged in a nifty carton with a fitted foam insert. Included in the box was a pair of gloves so that you don’t get your greasy fingers all over your nice, new bulbs. It’s a beautiful product presentation and gives a real sense of value to the whole operation.

Installation was easy as pie: remove your old bulb and insert the new one. The dimensions of the Oxilam are nearly the same as a standard H4 bulb so you don’t have a big heat sink or cooling fan jutting out the back of your headlight housing.

The Oxilam has a tiny cooling fan built into the front of the bulb. That worries me a bit but I’m rolling the dice here. Some reviews of the Oxilams claim the fan to be noisy. I don’t see how such a tiny fan can make much noise and I can’t hear it.

I couldn’t find a watt rating anywhere except an ad copy line stating the bulb draws a similar amount of current as a standard H4 so computers will not act up thinking a bulb is out. Lumens are a claimed 18,000 so I guess that’s good.

Maybe not 500% brighter but the Oxilam LED bulb is noticeably brighter than the original 24 year-old halogen bulb it replaced. Low beam is a lot better with a sharp cutoff so you don’t blind oncoming cars. Low beam is wide and bright.  The 6500 kelvin white light makes colors pop a bit more at night. Grass looks greener and the road edge is more obvious. The light produced is evenly distributed without any hot spots. It’s really wonderful. The Oxilam is worth it to me for the improved low beam performance.

High beam was also improved but not as dramatically as low beam. High beam seemed to reach a little farther out than stock and the white color was nice. One drawback to the increased lighting power was that reflective road signs were very bright on high beam, bright enough to cause me to drop back to low beam until the sign was passed. Installed in the ZRX lens there is an overly bright spot 10 feet ahead of the front wheel, I feel those lumens could be put to better use 100 feet down the road. I suspect the Oxilam will project differently depending on which headlight housing it is installed.

The Oxilam bulbs are worth the $39 to me. With my creaky vision I need every advantage I can get at night. It was actually not bad riding in the dark with the Oxilam and the new bulb will extend my riding time by a few hours each day. That’s got to be worth something, right?
