s13 gauge cluster lights delayed...

[boost_creep]

1992 s13 coupe w/ HUDi've noticed since i bought the car a year and a half ago, that every time i turn the lights on, the cluster takes an extra second to light up.this is my second s13, so i know its different. this normally wouldnt really be an issue to me, but the other day, i turned the lights on and the dash didnt light up at all. i turned them off and then on again, and they were more delayed, but then lit up. if anyone has had a similar problem, please let me know what i can do. the car did have an aftermarket alarm in it when i bought it, but i took it out. could it be because of this? any help would be greatly appreciated.
