Blue7-  Yes the new CC LED lights are E marked,

Tim, 

The lens may be but the comply, as may the red bulb but they will not have been approved as a unit - not hard to see why when you follow someone with them. 

Red bulbs fade rapidly,even when new the colour these offer varies as does the output ...

These would not pass IVA which is why CC used the old complete units which were approved, if your running clear lens with red bulbs Tim I would seriously change them, they are really shocking in terms of performance,  switching to LED bulbs alters the angle at which the light hits the lens and therefore output varies depending on the viewing angle.

Thumb Up I agree about the red led bulbs, I tried a few different types and they were all useless in clear lenses.  It is why I thought Doug's solution of an outer facing card was (excuse the pun) brilliant.

I keep looking at options as I've had reports my orange/red lenses and traditional bulbs are dire.

The LED replacement bulbs seem to have a lot of LEDs pointing towards the back panel so I think these would be better suited to the front indicators. So at this point I'm erring towards the panel type LED units For the rear.

I do get the E mark argument and the potential issues arising, however, I feel that the risk is worthwhile especially as it is trying to remedy a potential safety hazard. Unlike non E compliant headlights, rear lights are unlikely to cause an accident IMHO. Many OEM LED headlights are a safety hazard already as they are too bright.

The other point to make is how many of our cars are exactly as per the original build specification? Some of us drive heavily modified cars and unless every single modification is declared, we run the risk of our insurers having a get out clause. 


Finally, I remember a post from several years ago where someone had found some plastic highly mirrored concave reflectors that could be fitted behind the bulbs to improve the rear lights (though these probably affect the E marking status!)

Just for the record JAL lights have never failed an IVA or MOT. One IVA inspector was quoted as saying that JAL lights should be fitted as standard.

Blue7 is correct in the fact that the legislation has simply not kept up with technology. There are numerous instances of modern car manufacturers 'bending' the rules in their favour but ultimately making their cars better. Wrightpayne is also correct in pointing out that many of us already drive heavily modified cars.

The whole point here is safety, you are much less likely to be involved in an accident if other drivers can see you. JAL has upgraded thousands of Caterhams around the world without issue. In fact, our lights are still so popular that we have sold out again!

As for worrying about your insurance company not paying out, that's simple. Tell them! I have told every insurance company for all my Caterhams that I have upgraded to aftermarket LED rear light panels. They are more than happy to add the modification to my policy free of charge. In fact they are happy to add anything that makes your car safer and less likely to be involved in an accident in the first place.

Here is a video from James Morris showing how bright JAL lights are with clear lenses and high level brake lights. Video Link

Be safe everyone

Good post Doug Thumb Up

Yes, I recall that discussion. circa 2013, I don't recall the description but they were expensive and I wasted money buying two and cutting them to shape.  They made little or no difference and after a year had corroded and discoloured, you would get a better result using cheap reflective tape.  Having said that it is a bit Heath Robinson compared to what is now available in the form of either Caterham or JAL LED upgrades.

Here are my thoughts. After a foggy morning in the Peak District our cars were invisible with standard bulbs or even LED bulbs. I changed to the JAL rear PCBs which are significantly better, preserve the original look and are sensibly priced. Personally I would prefer to take a step towards reducing the risk of collision in the first place. 
I fitted them knowing they were not E marked. In my opinion I think an insurance company would be very hard pressed to prove that a vasty improved light over OEM contributed towards an accident or that with original lights the accident wouldn't have happened. This is the only non-standard item on my car.

Presumably your lenses are E-marked though? I"ve done the same. JAL inners, e-marked lenses. JAL rear fog and High level brake lights too. MUCH more visible. Much safer. Especially in rubbish weather...

Yes the lenses are the standard E marked ones.

Bacofoil over the reflector. Small improvement, cheap and almost indestructible.

Clear lenses are silly.
