every bulb on my 98 eclipse works other than low beams changed bulbs and still nothing looked under the fuse box and found the highbeam fuse but wast sure witch one is for low beam any help?
 
I find it strangely interesting that a company would put a FUSE on a headlight circuit. Are we sure they are fuses? Most manufacturers will use a circuit breaker so the lights don't go out and you are left SOL. Just a thought.
 
It's a 40 amp "fusible link" which is a type of fuse that blows when it's specially designed internal wire junction reaches a certain temperature and melts (same end result as the normal melting fuse). It also supplies the tail lights and the "S" terminal on the alternator. They are used in high current loads where you want a slow blow characteristic because many loads are constantly turning on/off.

[Circuit breakers are usually fast blow which is not good for larger current automotive situations where blowing a fuse is rare and a very short higher current spike is typical like when you turn on/off a blower fan or something inductive. And typical spikes you normally get in a car would be tripping them constantly. Circuit breakers are great for radios and electronic equipment where you want a short/overload to be terminated immediately to save the equipment OR where humans are constantly plugging in too many loads on a circuit so they can be reset easily.]
 
As an EE, I am quite familiar with fusible links but in my eyes, I'd just hate to have a fuse give out at any speed on a headlight circuit, but I don't design these things, I just mod em.
Engineers don't think about the things some of us do so I guess I shouldn't fault what I think is bad.
