Did you double-check if the high-option headlights are compatible with your e-Golf? There might be specific hardware or software requirements that need to be met.
Glad to hear your e-Golf is still running strong, even with those wonky charging lights. If you're handy, you could try checking the fuses or wires around the charging port. But if you're not sure, it's probably best to let a pro take a look. They can figure out what's wrong and fix it up.
I've had great luck using the SeaSucker Mini Bomber on my Kia. It's a simple setup: the main part goes on the back roof, and the suction cup attaches to the trunk. No problems so far.
