2000 Chevy Silverado 2500, light flash

ive installed some off road lights on my truck and im wanting to wire them up so they flash with the parking lights when i unlock my truck, but i dont know how do go about doin this, its a stock alarm system, and i was going to just tap into the parking light wire but when the truck is on they are on all the time, and i need these lights to be off wile driving, if anyone knows a way to have my lights flash with the alarm unlock but stay off when driving please tell me, thanks

have a relay turn on your off-road lights using the signal from the parking light. Using a second relay, have the ignition break the signal of the relay when it is on. this means if you turn on your parking light from inside the car, the off-road lights will be on too. But, it will turn off with the ignition on. You can still use your switch to turn the off-road lights on whenever you want. Note: You Always Dont Get What You Pay For.

ah didnt think of that at all, thanks a bunch
