I've got the Kaymar light pole on my spare wheel carrier and I use this Hella work lamp. It's got twin 55W globes and has an excellent spread of light for about 10 meters either side of the vehicle. Being mounted high also helps. I used to have this light on my SIII and it was so good in comparison to the original Kaymar cheapy that I just had to swap it to the Defender.
