Glow post & rail markers-set i.e. 1 green and 1 white post

Do you want to make your driveway safe at night. The posts glow and reflect light at night.
The day colour of one post is green and the other post white. Each post has a small hole at top and bottom.
The 6 glow arrow heads on each length are yellow at daytime and glow green at night.
We have limited stock left, although we have a few more white posts than green ones.
Size 51cm long x 8cm wide. Made from aluminium.
Postage is an extra $6 per set
Please advise day colour if you are ordering yellow posts only. Otherwise you will get one green and one white post.
