New Auto Headlight Headlamp Sensor Chrome Switch OE: 5ND 941 431 B

Ridiculously easy to install.2016 Jetta Sport. What’s bothersome is VW did not put this part in at assembly! Would have cost less than $5 for the part at their cost. More like $1 at bulk pricing.Anyway, works well. However, has to be quite dark to turn on. At dusk it may or may not turn on. So be aware. I placed mine on the very left of the dash closest to the left side mirror. Using the window frame as a ‘cover’ so when it gets dark it is already shaded so will be darker in that area. Saw another post placing in the foot well. That fine but then most likely lights will always be on.... not a huge deal I suppose. May go through more head lamps over time.

All functions work except the auto, has to get very dark for them to work.

This worked perfect with the ECS wiring harness I installed for fog lights. Easy install easy programming and cheaper then OE.

You can never fully turn off your lights. Easy to install. I still like it. Just wish I could turn the lights all the way off.

Easy to install, I recommend watching an install video before starting. It is very easy, and works great.

Words as described and East to install.

I can’t find a way to turn on my fog lights

Instructions are in Chinese so use Google Translate app to translate.I don't see a sensitivity adjustment so that the lights on sooner as when it's beginning to get dark.I have a workaround, I placed the light sensor in the footwell area by my knee where it's darker so that the headlights turn on sooner without being completely dark outside.
