i have a 92 prelude si with a h22 swap, but my dash lights work fine during the day, but at night when i turn my headlights on , even when i turn the dimmer all the way up, there is no light on the speedo or the tach, also my fuel and temp gauge about halfway disappear.....i am completely lost as to why this is like that.... any clues??

 

anybody??

 

Well your car doesnt know when its light out or dark.. So they arent working fine during the day.. check your fuses, then replace the bulbs. still doesnt work, youve got electrical problems...

 

well the heat and temp go duller with the headlights on because headlights use energy but with your dimmer, you should be able to control it.
