If you have a burnt out LED turn signal you will not get the quick flashing of the left (or right turn) arrow on your screen as with all ICE cars. I noticed I had a burnt out front turn signal light not working by visually checking the front of the car. The problem is that it can’t be replaced. Tesla service said I have to replace the whole headlight on my 2018 Model 3 with 86,000 km. The cost to replace is $1500 for an LED which probably costs 10 cents. Has anyone else had this problem? Before you say no, visually check. Pretty sad that they are designed this way.
