My old cluster had an aftermarket "flasher" bulb that indicated that the car was locked and armed. It came with the power locks / alarm kit. I wanted to preserved this functionality but I
didn't want to drill into the new cluster. Instead, I blocked the word "anti" on the cluster and made the word "lock" flash. Since the alarm module
outputs 4V and the cluster bulbs are 12V, connecting the two didn't work. I tried boosting the voltage with a transistor but still no luck.

Instead I desoldered the dimmer red LED from its wire and soldered a white LED instead. I got it from RadioShack, the brightest I could find. I wrapped it in paper and stuffed
it in the cluster, right behind the "lock" indicator, in the bulb socket shown.

The end result looks like this:
