Rear Light Style Advice

[rbt1548]

Hi I am going to look at a 1970 CB750 K0, UK bike, quite close to me, I have only seen a picture so far and was not sure if it had the correct style of rear light and bracket for that model as I have seen some pics on the internet with 2 differing styles.
Are they both correct but for different markets?

The one on the bike in the advert has a black bracket ,similar to the one in the picture which has a support piece going towards the seat direction, basically shaped like an inverted "L", it has a rectangular rear lens with straight ends, is the bracket correct for year, should it be chrome, and is the lens correct?, I have also seen a pic with a lens that is rectangular but has rounded ends.


The other one I have seen is chrome with just a vertical arm, like pic below, this one seems to be more widely fitted.


Any help appreciated ,
Thanks

Top bracket is UK style and bottom bracket US and other countries style I think?, US had big back lights and UK had smaller ones  cheers Mick.

I think originally they were black ? but you can also get them in chrome , there's that many variation's of them cheers Mick.

On the 500 the UK was black and US was chrome - 750 same?

  yes mick is right the top  black "L" bracket is correct for uk market the lower is USA and a dead giveaway on any imported bike. but the square  light lens is only for the K2's onwards. the 1970 k0 should have a oval lens and not square edges
