Hey guys not really a problem but more of an idea... im thinking of hooking up an led to the temp gauge that starts to flash when the car gets hotter than normal operating temp but before overheating.. (a warning light) im thinking i could use an old turn signal switch and relay for the led flicker but how could i get it to set off at a specific temperature?? i just figure it would be nice in case you happen to for that one split second forget to check your temp gauge or like while your drifting for an led to flash on the dash kinda like the seat belt warning light or shift light so you know to let the car go cool off... anyways thx :driving:
