Thanks Rob...as always! I just bought 4 of the green ones, that's the glass only. I'll make up the brackets for them. The question on the Red ones was just that they had exactly the same size, but in Red. Just wasn't sure whether they were on any of the vehicles....front or rear. If you can send me a photo of the trailer "T" sign, I can see if there are any there to match them. I know I brought up the T sign a couple of years ago, on this forum, with the idea of reproducing them.
I know there were some questions put forth about these reflectors by a number of members "Down Under" regarding the various colours.
Thanks again Rob......Robert
