Q: When I set the alarm only the left side indicator lights flash, the right no light flash. the alarm work OK.

asked by on

I would like to know why only one side front and back indicators lights do not flash when I arm the alarm. Apart for that the alarm work fine, it's not a big problem but annoying.

My car has 100000 miles.
My car has an automatic transmission.

When the alarm was installed the alarm output wire for the lights need to be tied into a parking light circuit or turn signal circuit. Whom ever installed your unit hooked the light output wire to only the left turn lights. There is not a problem and if you wanted it to be fixed it would need to be rewired.
