i changed my headlights to a superwhite bulb and when i did so i blew the fuse... it was a 10... this was in the shops parking lot so i just went in and they gave me a 20 fuse... said it would do the trick...

NOW, today i went to fix the fude on my fan and noticed my 20 fuse that was handling the headlights was melted completely... the metal was still intact and the fuse was still getting power to the headlights but the plastic was in a hardened puddle inside the fise socket....

WHAT GIVES>>

 

u probably have the wrong bulbs. i just changed the stock lights on my 2001 f4i 2 weeks ago. i used the eurodezigns h7 8500k- it is very bright and has that bluish white look like the headlights on my dads bmw.

 

Thats what i have on there... h7...

 

But they are probably higher wattage then the factory blubs. That will burn up your fuses quick. Be glad you didn't burn the wiring harness and catch the bike on fire. Pull those headlights out and put the factory ones back in ASAP.

Headlights have different wattages of output. The wiring is only rated to handle a certain wattage unless you upgrade the wiring. I've seen people burn down their cars & bikes that way.

 

i fixed my problem but i left the lights in... i was runnign the high beams all the time before it melted.. im goign to try only running them when neccessary and seeing if that helps... also do you think a better fuse liek 30 or higher woudl work or is it going to burn the plastic regardless.. in which case i should take the bulbs out

 

Dude -- please find out what wattage you're running now. There are 55W H7 bulbs all the way up to 130W H7 bulbs. Any H7 bulb will fit your bike but you should not run anything higher than 60W. Period. The only exception would be if you ran new wiring to the lights -- and you don't wanna go there.

UNDER NO CIRCUMSTANCE SHOULD YOU PUT IN A HIGHER FUSE -- IF YOU DO YOU WILL REGRET IT!!

 

that is correct. fuses are put where they are for a reason. If you put in a larger fuse than what is recommended you're just asking for trouble. [sm=badidea.gif]This is a rule of thumb for ANY electrical operations; cars, trucks, minivans, motorcycles, boats, vibrators...whatever. If you overfuse something its not IF its WHEN,[sm=badbadbad.gif] and you WILL end up frying/melting something and its going to cost you alot of time and money.

Well said Chain and Addict. If you put in a higher wattage fuse, you do so at your own risk. You will catch your bike on fire. The fuses are rated at a certain amp for a reason. Put your stock lights back in and let it be. All you need is to use the high beams at night and have the fuse blow and wires melt, then at the best case, you have no headlight at night.
