LCM 2500 for GM - Lights That Will Flash

Here is a list of lights that the Z-Flash LCM 2500 for GM can flash on your vehicle:

High Beam Headlights

Low Beam Headlights

Turn Signals

DRLs

Reverse Lights

Brake Lights

Cargo Lights

Tail Lights

License Plate Lights

Center Mount High Stop Light

Fog Lights

Please Note that this is a general overview of the lights it can flash. Some of the EV vehicles could have some differences such as the Hummer EVs.

Reverse Lights

If your Reverse Lights are not flashing please make sure to turn DIP Switch #3 to the ON position. We provide the option to disable these from flashing as we understand some users may need to disable the white lights from flashing.

Red Lights

While the Z-Flash does flash all the red lights on the rear, we offer the option to disable those. If you cannot flash any Red Lights in your area, you'll have to use Pattern 5 on the unit.

To change the pattern simply hold the button down for 1 second while the Z-Flash is on. This will change the pattern and your dash will flash the x amount of times depending on what number pattern you are on.

DRLS

The Day Time Running Lights (DRLs) are tricky on some vehicles. These are sometimes not able to flash and not guaranteed. On most vehicles they will flash, but if they do not it could be related to the vehicle's trim level as well.

Mirror Lights + Clearance Lights

A common question we get with the Z-Flash LCM 2500 for GM is if this will make the Mirror Lights and/or Clearance Lights flash.

These are not guaranteed to flash because the Clearance Lights/Cab Lights and Mirror Lights on the GM trucks are not on the same lighting data that we are connected to when installing the Z-Flash.  

Generally if your Mirror Lights also do the Turn Signal function they should flash. Even then it is not guaranteed to flash.
