[8D] my security light does not flash when arming system but alarm does work how can i fix this.

thanks in advance

 

If its a bulb, replace. If its a led, replace with superbright led (gives bigger bang between the woulberobbers ears).

If its neither, check wiring, take out /resolder alarm module.

When all has been done/broken *1, buy, replace with new 150$ alarm and spend one week dechiptering mfg cryptic self contradicting manuals (whatever dont buy german Defa), install in 3hrs.

*1 my experience...
