Have sent a note to Kim and Karl asking them to look at the problem.
Had 20 watt bulbs in my (brand) new boats lights, unfortunately the units were rated only for 10, this caused the plastic covers to warp slightly and fall out at random! They wouldn't then click back into place. This was however only (a minor) one of the 21 problems we have had in the 2 months of owning it!
We hope to make it to Dartmouth ovre the bank holiday assuming summer returns!
