Trailer socket query for you sparks out there...

Can anyone tell me just from this photo, which one is the earth, and which is the brake light? (Yes, I know I should really use a multimeter, but you guys are so smart!)

take your pick from here.

assumes your plug is correctly wired though.

Now sorted, earth = 3, brake = 6... cool...

It's just a 'bit of nonsense' project LOL My car came with a towbar and I've never used on in 40 years of driving. I have now modified an additional LED brake light which can be mounted on the ball hitch. I may be old, but still have the heart of a boy racer!

Make sure it doesn't sit too low or you'll get nicked.

In my GT4, that's quite possible. I'm hoping in a sedentary old Merc, they'll just ignore me!

Now, I feel stupid! I'm a massive F1 fan, never tied the comment with it! But now you mention it, hey, that's a great idea - I could wire it up to my LPG cylinder to flash when I'm on gas LOL

Just to round the thread off, here it is in action - reckon I can get some go faster stripes next LOL

That's hilarious buddy! The clue is the last photo where you can see the light now working - all info gathered a while back. Now, I'm going back online to choose my furry dice!
