Have been asked a few times about the solar PIR external light that we have modified to hook into the vent panels so thought we would post it here in case of use to anyone as it works well. Currently £11.49 delivered on Amazon http://www.amazon.co.uk/dp/B008VB4TNO/ref=pe_385721_37986871_TE_item With just a simple modification - it is quite malleable aluminium - we have bent over the back section to enable it to be hooked into the grille on the panel just below the awning - see photos attached. We attach this on arrival at site & detach for travelling - it is very effective & lights on on opening the hab door (good position on our Chausson), when approaching the motorhome & when moving around outside. Only downside is if it is under an extended awning it loses charge after a couple of days but soon remedied by putting in the sun for a few hours If you don't have a grille in a suitable place then probably not much use (unless you can think of another removeable weatherproof method of attaching the light?) but may be great for those that do!
