We have just come back from a month in France.
The last time we went I used commercial aids to mask off the dipped beam.
Being clever , I recorded where they were positioned on the headlight.
This time , like many , I used black tape to block out the required area.
On each headlight I stuck on two short bits of Gorilla tape.
No problem you might think.
However when it became time to take the tape off , did it come off easily?
Yes it did.
But what did not come off was the adhesive underneath the tape.
This had etched it's way into the polycarbonate surface, maybe 0.1mm deep.
This meant I had to polish it all out and it took some time , it needed doing anyway since they had yellowed this year with UV.
It's an old van now , 2008.
Next time I'll use electricians tape 🤔🙂

I bought some of the proper masking things from Eurolites, which are sort of teardrop shaped. Left them on for four years then last year thought I'd better change them having heard a few horror stories. The polycarbonate lens covers underneath were in perfect condition.

I just don't bother - can't remember the last time I drove in the dark in Europe. I'm on holiday and chilling - never drive late.

So you don't drive through tunnels or in the rain then, where lights on is a legal requirement ?

We don't drive late either - but we have driven several times through a storm etc and needed headlights on.

Interesting comment from OP - on our old van we had polycarbonate headlight protectors which had a masking area marked out, and I made masks from sticky backed plastic. Unfortunately the protectors don't fit securely on our new van, so I'd been thinking I'd probably get the beam bender type.

Nor me. I have a set with me, that I can fit in a moment or two, just in-case I have to travel at night. But otherwise, I don't bother, either.
Yes , noticed a lot of vans over there didn't bother.

When I have used the blockers, carefully ensuring the placement is correct, I've found they either don't block the light spill much at all, or they make the lights as effective as candles in jam jars.

Yes , on another trip from Santander to Portsmouth our van was outside on the deck.
On arrival I washed as much off as I could given the 15mins between access and unloading.
How I made my way to Marina Keep I'll never know.
I now have nightbreakers which I admit we're pretty good this time (X250)

enough to know i shouldnt touch things i know nothing about ....
The residue though from previously using electricians tape, demonstrates that my beam benders must have fallen off, honestly Monsieur Gendarme....

I think part of the issue is they get pretty hot. The adhesive bakes on and attacks the plastic.

The other issue is that once you've polished the polycarbonate, you've taken off the protective coating. So it yellows, spiders webs and gets marked more easily next time. Some of the headlight polishing kits come with a resealler... not sure if it works. But I used a polishing kit on my previous 2007, then I put Eurolites on for 6 months while we travelled Europe (in 2019). They came straight off with very little marking.

You was lucky, Eurolites should only be left on for a few weeks. I used to sell them, lots of people left them on too long and had problems.

In over 30 thousand miles in Europe I’ve never been flashed when I’ve had my lights on…

I don’t use em… or any other sticker…😎
Same here. I did buy some but decided on this new VW Crafter not to fit them. Impossible to find the correct position anyway and like you say never had anyone flash to indicate a problem. Saying that we don't drive at night really. They now reside in the cupboard next to the angles mort sticker:LOL:

The stuff created by the devil. Always leaves a residue, will pull tufts out of carpeted floors, and take paint off woodwork. Get proper gaffer tape from someone like CPC. If you are paying under a £10 a roll it's not the proper stuff.

That said, we have clip on polycarbonate covers with the areas masked out. They work well and take 2-3 minutes to fit or remove.

What about motorway driving in the rain during the day when you have to have them on?
