They're definitely illegal in England (sent my brother over a couple of neon sticks for his car, only lasted a week before the cops pulled him over!) The cops said that any unauthorized lights are illegal (whatever that means?) and that his was especially bad in that they were blue...
They're not that expensive, least not in Japan. Have heard they may be illegal here too, but I have been driving around with them for nearly a year now and never had any trouble.
I'm driving around with blue neons, but you can get green or pink (if ya so inclined!) You need to get reasonably powerful lamps otherwise the ambient lighting (street lamps) washes a lot of the effect away!
240 CAD. Is for a full kit here in Canada. I know their also illegal here however I guess police are too busy doing other things to be bothered to ticket them. However I have heard tickets being issued for...
1. Rim size too big.
2. Exhaust tip too large.
3. Vehicle too low.
All of them were thrown out of court of course, but I think the police are just tring to make extra cash. They get paid to make court apperances, where as for us it is just a plain nuisance.
UK law states that so long as you can't see the lights themselves you can have whatever frikkin colour u want. Proper neons shouldn't be seen - only their glow should be seen. This is perfectly legal. So long as you take care fitting them and none of the neon can be seen from anywhere outside the vehicle then you should stand you ground if pulled. Not alot of coppers know this though so be prepared to politely advise them that the lights aren't visible - only their glow is - therefore you aren't breaking any laws.
Now that someone else has come out o9f the closet I'll stand up and be counted too - I quite like them and will be getting some blue neons for my silver R32 at some point. Quite unashamedly Barryish, I know, but I really don't give a fcuk what anyone else thinks.
Flashing blue neons - hmmm.. I think these ARE illegal, as the coppers can do you for impersonating a police officer (which is entirely subjective and doesn't involve highway laws therefore you can't say "But you can't see my lights directly..."
If you can find ultrabright LEDs in frosted polycarbonate tubes then they're much better than neons. Neon tubes break, wear out etc. LEDs on their own look very Battlestar Galactica when the road's wet as you can see the LEDs's reflection as lots of dots. You can buy LED strips in frosted polycarbonate casing (indistructible and the frosted bit means that the light is diffused and you have a more even glow to the strip than the individual LEDs would give).
I got told similar, as long as the actual tubes werent visible....
Just found another set, LED, with loads of programmable modes and 7 different colours that it can rotate through as well as increasing/decreasing intesity, swapping from side to side/front to rear etc... they look pretty cool.
You can get neon kits for as little as £50. You need to make sure that you get a kit with two long tubes as well as two shorter ones, as many kits cater for Saxo/Corsas etc. which are alot shorter than Skylines, so making sure you get the longer tubes wil ensure that the "glow" extends the length of the car, rather than being a bright blip in the middle of the car like some sort of searchlight for roadkill...
