Thanks for the heads-up on the two brands! I've bookmarked the LASFIT LEDs in case these Alla LEDs puke.
I plugged the Alla (921) LEDs today into my 3rd brake light & 2 cargo lights. They had amazing output & all AOK. Then I heard some clicking sound by the passenger taillight and what sounded like air leaking in the engine. The truck was not running at the time.
I looked in the cab, and the dash, Nav system and other lights were all flashing. Also get numerous engine error messages and other error lights/icons. The truck would not start. I plugged in a error code reader and no codes were detected.
Replaced the Allas with original bulbs, same errors, lights & sounds. The battery was barely 6V and sound of air was the vacuum pump periodically cycling. Truck still not running.
I also had the Tazer DT plugged in but removing that did not change anything.
It took about 10 minutes to jump charge the battery and it finally started, but still flashing & blinking and many errors. I drove for a few minutes and a couple codes & error messages disappeared.
Drove 35 minutes to the dealership and all codes, errors & messages were gone before I got there and all safety & other features worked fine. The dealership was going to look at on Monday.
Not sure how 3 LED bulbs could f'up the computer or other systems so much.
I'll report back after the dealership has looked at it.
