Fair question to ask... When alarm is set off or you set the alarm and the turn signals flash on and off. Well. I put in a new alarm and it did it fine but now suddenly no lights will flash with my alarm but only you hear sound. What could be wrong, can I fix it myself? and or what should I do.. thanks

 

i would think that the wire that is connected to the parking lights from the alarm has become loose . . . or perhaps a fuse?? if u got it installed by someone i would just take it back and ask them . . . . .

 

Either that or you inadvertantly changed the response by holding a button/combination of buttons. Depending upon the alarm of course.

Not terribly likely, but it's a possibility.

 

You either 1. Bought a cheap alarm. Or 2. Loose connection. In either case I would take it back to get it checked.
