Is this the factory alarm or aftermarket?

It may be that the LED wants to draw more power than the brain can provide.

Another thing could be matching the LEDs to each other. Meter the old LED and see if it is a resistored LED. If so, match the new LED to it.

Another thing to try is to re-attach the old LED and meter how much it is drawing, then find another Blue LED that matches or draws within 10% of the old LED.

Last, double check all connections/solders. If soldered, a commen problem is a cold joint, a joint that doesn't conduct electricity easily. It should look shiny, convex, and silver. Any crimp connections should be clean and well connected.

Hope this helps. Good Luck!

I'd bet that the blue LED and the red LED have different Vf ratings.. it might be easier to grab a signal from the circuit that powers the red LED and use that signal to control a transistor to flash the blue LED
