tesla cybertruck fans are going crazy Latest OEM accessories for trucks:A light bar It is installed above the windshield and blinds all oncoming traffic with its abundant lumens. There is only one real problem with the light bar. It’s illegal to use on the road, and it’s even illegal for Teslas to install it on their shiny new trucks.
marques brownlee Posted on Twitter about his Cybertruck’s light barsaid the lights arrived only partially installed, meaning the front was covered with blackout tape and the wiring ended inside the cabin without touching the power lead. After delivering the car with the lights half-installed, Tesla sent Brownlee the name of a local shop that could complete the installation without bothering Tesla.
This seems like an odd way to attach an OEM accessory, but it’s actually a perfect match. tesla service manual For Cybertruck. The manual is chock full of warnings to Tesla technicians, stating that under no circumstances can you complete the light bar installation yourself, and to maintain Tesla’s full involvement, please visit your local shop. tells you that you need to do some wiring.
By the way, the wiring here is a mess. The light bar connects to the Cybertruck’s “Roof Accessory Jumper Harness,” so you might think the truck has an unused wiring connector to which it connects. no! The “harness” is three wires that stick out from the roof of the car and terminate in heat shrink tubing that must be soldered to the light bar wiring.
For those who have never worked with automotive wiring, soldering is generally a bad idea with car accessories. Cars, especially those that drive off-road, vibrate. As you would expect from a truck with a light bar that is not legally roadworthy. That vibration breaks the solder joints. everytime. Although crimp connections and plugs are much preferable from a reliability standpoint, crimp connectors and plugs are costly. The solder is supplied by third-party shops willing to install road-legal accessories on brand-new Cybertrucks, and it doesn’t cost Tesla a dime.
Not only is Tesla’s workaround shady by using local shops to circumvent street legalization laws, but the Cybertruck’s actual wiring is equally sketchy. The wires, which are functionally installed on the outside of the vehicle (covered only by a thin piece of metal on the roof), are simply twisted and soldered, rather than crimped or plugged. In fact, this light bar, like its other accessories, aptly sums up what Tesla is all about. That means it’s poorly designed and of questionable legality.
