Acerbis Brake/tailight= Junk

I bought an Acerbis brake/tailight, thinking I was upgrading from the stock television set. Woe unto me, the thing was built so cheap it worked for about 10 minutes, after replacing the bulb 3 or 4 times and bending the contact arms and constantly having to work on it to keep it working. I finaly fixed it. I cut the whole bulb mount assembly off the back of the reflector, bought a 3157 bulb holder and pig tail from the auto parts store, after a little time with a dremel tool got the hole the right size in the reflector. I put a little silicone rtv on the bulb housing and assembled it all. Wallah, 2 days later everything works fine. Finally, I am happy with my tailight! So if you purchase one of these pieces of work get reay to spend another $10 and about an hour of your time making the light dependable!

Although I don’t have much time on mine (10-15 hours) it has been dependable. When I began reading your post I thought it was an electrical problem causing the bulb to frequently burn out. But as I read on it sounds like the new holder that you installed corrected the problem. Is there something obviously wrong with the original holder compared to the new one?

YES, the contacts on the bulb holder are weak copper arms, that easily lose their tension and the fluctuation in the connection causes the bulbs to burn out. I even tried soldering the bulb contacts directly to the holder arms, lasted a few days. then the bulb burnrd out. since replacing the holder I feel I have fixed the problem. Have spoken with others who have had similar problems with acerbis electrical parts. Some have stated that acerbis seems to be electrically challenged, and they should stick to plastic, and clothing!

Very cheap manufacturing. I had one and it caused me way to many problems. Could not be relied upon at night.

Thanks guys, before I buy anything else for my bike, I am going to start a thread about it, cause I am sorry I bought the acerbis light. You guys are the best testimony a person could ask for when it comes to mods/ upgrades for the big thumper.

Nice info! I need that as I was looking into this exact swap!!

Thanx guys,

Bill

Acerbis lights dont carry a great rep, thats for sure.

Hey Justice

Are you satisfied with the one you got from 4Strokes Only? Is it DOT? Does it have clear bulbs in the bottom for the light? I ask, because i am about do to this as well!

Thanks

I have been happy with mine, it has a small clear plastic area to light up the plate. I do need to get a new cover for mine as it has a hairline crack starting. I suggest ordering a spare. If you look closely at the pic in my garage, you will see how i used a pice of the stock rubber to cover the wires. I also would get the pice of rubber to bolt your plated down, will keep it from rattling, chaffing or coming loose.

I just fixed exact problem! First bulb kept burning out! Fixed that problem by putting in a rubber thing/ bracket to keep bulb from bouncing breaking. That worked great until the heat from light melted the plastic housing so it would not hold a bulb. Figured that if tried again with LED light temp would not be a problem. Went to baja desingns where I purchased first shock resistant housing, but they dont carry any more. Completely fixed problem by going to auto store buying metal housing and placing it in rubber holder! LEDs arent that bright so stayed with stock bulb, but problem has been eliminated!!!

By the way - the Bajadesigns LED light (4436_fresh_rubber.jpg) may look good, but it's not waterproof. I bought the bike with that thing installed and it took 3 puddles to get muddy water inside (it was installed properly)! An hour of disassembly and almost destructive knife and screwdriver glue-cracking later, I was able to clean it out and then seal it with silicone. If you buy this light, plan on sealing it heavily before it fills up with mud.

I love my Baja Designs LED taillight. It is bright, looks cool and very reliable, had it about a year, never a problem at all. Uses no amperage either so my battery on my XR610R Supermoto stays charged all the time.
