my flasher keep flashing even tho my truck is off
my 97 dodge ram 1500 slt run very well but when i put some emergency lights and a siren (in a voulenteer firefighter) on my truck my flashers blink when i shut the truck off.. i disconnected the battery during the install and it started when i connected everything back.. also theres a red light on the dash that is bliking also its next to the O/D button and it diddnt blike beofre that either.... if you could help that would be great.. im thinking its my battery maybe i just need a new one ?
