Headlight covers, even without tint, reduce the amount of light that can get out to show where you're going: two extra surfaces, each of which takes at least 3% of the light away.

Then they get dirty. That's three surfaces getting dirty not one. Much more light lost in rain, from road spray, and if its freezing, from road salt. Don't expect to see much.

Tint them? Well fine, your choice, but you can either look cool or see where you're going. Not both. Unless you're never going to leave the built-up area with its streetlights.

Dont those clear bra places have that ? Ive seen that for other cars.

A thin 3m plastic film.

No need for actual plastic parts

Have to say I agree, I personally think the tinted ones look gash. Makes the car look like the car has those old person sunglasses on that go on over their glasses.

I think the lights break up the front end nicely. Adding a cover over them ruins the smooth lines

The other problem is cleaning them; most I hjave seen end up going green and manky.

Each to their own but not my cup of tea.

Yep, I'm positive that sticking any cover in front of the headlights will degrade the light output significantly. The eye adapts to ambient light levels so you may not notice the reduced range until you hit that pedestrian/cat/patch of oil/tree, unless you do a direct comparison with an uncovered set of headlamps.

The film covers mentioned above are a much better idea. Properly index-matched to the headlamp glass, they could add less than 1% to the light loss. However they all seem to be designed firstly as paint protection films, so best to assume 3 - 5%. Still, it's only one extra surface (glass/film) unlike protectors that are spaced away from the light, so film is definitely the best way to go.

I spent money to get brighter lights (Philips Vision Plus) so I can see better at night. But I don't care so much about how my car looks (although I won't go to the extreme of fitting add-on spotlights, if you can get such a thing these days)

If you care more about looks than performance, then it's an acceptable compromise for you. I'm pointing out that you will do serious damage to your ability to see at night. Just be aware that it's for show, not go.

The Road Vehicle Lighting Regulations only specify a minimum power for the headlights (30 Watts). Oh, and they mustn't be red. Otherwise you can legally drive with a pair of 30 watt candles behind heavily tinted covers. All the prohibitions on brightness are about dazzling or causing discomfort to other road users. It is assumed that drivers will moderate their speed so as to be able to stop within the distance they can see. :(

I suspect there would be some heavy consequences if you had an accident through driving beyond your visible stopping distance through tinted covers, though.

I've had these covers pretty much since I got my LC. They certainly do the job protecting from stone chips debris etc .which I wanted having had foglight smashed within first month of ownership. The smoked ones look cool for sure, but not very practical except in high summer.
Keep them clean and they look fine as they are. ;)

Have you found Foglight covers?

No. I've made my own with plastic cut from a plastic beer 'Glass' sourced at BTCC. Cut a little oversize, and it slots neatly in between lens and frame to protect the glass. Probably cuts light output a little but does the job and looks fine except really close up.

"Plastic"-air interfaces are slightly worse than glass-air; you're probably loosing 10% of the foglight output, proovided you keep the covers clean. However, foglights are inherently short-range in any case, being more about keeping the light low down and diffuse so as to illuminate the edges of the road without blinding you with backscatter. The light loss isn't going to be a problem.

The main problem with any spaced cover is the dirt that gets trapped in the gap. That's why the film idea is such a good one.

thanks for some of the comments..

im really not too bothered about taking them off at night... its a 2 second job. even with HID's they do not let enough light through but i am going to do another set with half the amount of tint on so i can leave them on permantly.

Hey Up fella, what process are you using, We tried with a can of tint spray of Ebay ( probably the answer is there !) but it looked hideous.

the trick to an even covering is to not go mad for a start. tape up the front of the covers and stick both side by side...

then lightly cover both covers at once with alternate directions ie first do a vertical coat over both, wait for it to dry or go tacky (whatever the can says) then do a horizontal coat over both...

if you get any areas that havent covered then you'll need to clean them off properly and start again.

i hope this helps matey :)
