Four problems related to tail light switch have been reported for the 2018 Tesla Model 3. The most recently reported issues are listed below.
There is a buildup of water and condensation in the rear tail lights of my vehicle. The issue is known by Tesla as they replaced the same problem before, however, now they are not covering it under warranty even though it is a common problem among Model 3 owners.
Front fog lights and rear tail lights fogging and filling with condensation that could lead to electrical issues. Service center said this is 'normal'.
Problem: rear tail lights were not illuminated, even though the standardized headlight symbol/indicator was depicted on the vehicle instrument screen. This symbol is universally understood to indicate both headlights and tail lights. Incident: while driving on a dark and unlit road, I encountered debris blocking the road. In order to pass through, I exited the vehicle without turning it off and left the driver's door unlatched to ensure the vehicle did not inadvertently power down. I expected that the headlights and tail lights would remain illuminted to, both, light the road ahead as well as illuminate the rear for safety and visibility. After moving the debris from the road, I was surprised to find the rear of the vehicle was completely dark and not visible from the rear. However, the interior instrument panel simultaneously depicted the standardized headlight symbol, with no warning that the rear lights were independently turned off. This is a safety hazard, as the driver/owner has no indication that the rear tail lights turn off. Aside from manually going into headlight settings in the vehicle configuration menu, there is no easily accessible way to keep all lighting active while the driver is not in the vehicle.
Hello, I often follow Tesla Model 3 cars in dense traffic, and stop behind them at red lights. I have to say, their tail lights (more exactly, brake lights in the center of tail light) are extremely bright while being very small. They are almost as bright as lasers. When it's dark, looking at them even with peripheral vision is painful, I have to look to the side to avoid being blinded. I am sure looking at these lights is dangerous to my vision. Instead of these very small and very bright lights, Tesla should have used bigger lights with smaller intensity (emitted power per square inch). I am attaching a stock picture of Model 3's tail lights. Unfortunately, a camera could not capture the very high intensity of the light.
