An old post, I know, but you know how you stumble over these things.
Logo puddle lights are very fancy, but do they light up the puddle?
I fitted my Disco with LED strips mounted along the chassis. They are wired to the interior light, so they come on either when you unlock or when you open the door.
They show any uneven terrain, and ......... puddles!
On the same circuit I also installed a LED light that points at the ignition switch.
