There are 3 owner-reported lighting complaints for the 2004 Cadillac Escaladein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
When this device is used to replace the Flasher Module (my had failed so I ordered this replacement from Amazon) I found that the brake light circuit to any trailer connected tot he vehicle would no longer work. Under further research on Amazon via reviews and other online sources, I found that all of the Chinese clone parts have this same failure mode. Since most people check trailer lights with Directionals or 4 Way flashers, they would not be aware of the failure of the brake (stop) lamps not working on the trailer leading to critical dangerous situation if they need to slow as the driver behind them is likely to rear end the trailer due to the failure of the stop lamps to light.
