Recently, the rear left position light of the car turned on and off. When I saw the post in the group about repairing the taillights, I decided to try to repair it myself, and the effect was good. For your reference. In 8 years and 175,000 kilometers, the left taillight broke for the first time.
A total of 32.8 yuan was spent on Yuhong structural glue, which is available in the laboratories of other tool companies. It’s always on when repaired, but I don’t know if it will go off again after a while. In fact, it’s just soldering three resistors on the circuit board. The repair is very simple, but it is more troublesome to cut the shell, but as long as you are careful, everyone can do it. The right rear position light broke down before (it turned on with a pat), so I bought an original car-dismantling part, but it broke down again after using it for 2 years. I won’t buy it on the left side this time, do it yourself.

I didn’t use a grinding wheel to cut it, and I was afraid that I wouldn’t be able to grasp it. I used an electric soldering iron to melt the two holes open.

After sealing it with a soldering iron, I found another piece of black plastic and melted some plastic into it. The melted piece of plastic was too small and would fall. It was much better after adding some material.

I bought the structural glue recommended by Yan Edition. Personally, I think I can repair it well with a soldering iron. It won’t get into water, so I glue it just in case.

After applying rainbow structural glue, I originally wanted to buy black, but I bought it wrong and bought it transparent. It would look good if it were black
