Hey,

I have a set of crappy ebay projectors and the only problem with them is that the H3 low beam bulbs go out constantly. I have been told that it is most likely a problem of the heat diffusion or something like that in the housings for the bulbs... and that causes the bulbs to burn out. Is this true? What are other possibilities?.. could voltage or wattage or something like that be the problem? Also, please suggest fixes to whatever you think the problem is.

 

how much did you pay.

 

i know someone that fixed this by drilling vent holes in the bottom...

 

Yes, I was thinking of that, but will condensation of water be a problem? I noticed the caps that screw on to the back of where the bulbs go are air tight seals. I'm not so much worried about actual water getting in there but even the air could pose a problem, or could it?

When I bought them they were $160.00 off eBay... the price has gone down since then I think.

Thanks,
John

 

wouldn't you want to put the holes on the top ?

 

water would go right in

i just ditched my projectors in favor of jdm's

 

Why, I have a hood... And yes heat does rise... But still if condensation ever took place then the holes would be better in the bottom.

Anyone else?

 

Take a look at your OEM headlamp, seeing how they made a ventillation hole + ruber tube so that the vacumm will be sealed without condensation yet the oxygen will not burn all out? The same thing for your corners as well. Simple physics: Oxygen helps keep the "flame" going, so, without any oxygen, your bulb will be forced to light up, yet will shorten its life.

So try to see how they construct the thing and hopefully it'll help you out.

Other reason is that the overload input voltage and current (or their products known as Wattage) will burn out the bulbs. Check to see if the bulbs' wattage input is NOT LOWER than specified input wattage for your headlamp.

Sorry for my babling.......

 

Do you think that if I put a hole in the back of the projector housings and run a rubber hose from it facing down... about 2 inches long, will that work?

 

drill a small hole and then put a stick over it. I'm not sure if this works, but that's how ford does it for their F150 harley davidson edition.
