caravan marker lights

[Thomas-the-Terrano2]

our spectrum has a full set of uk markers arranged as follows

front outlines at bumper level, red/white on upper rear body sides
and finally full rear clusters with tail lights incorporated.

with darker evenings on way for towing to weekends away wondering
about adding more.

first thought was to add red/white side markers in area of wheel arch
to give more illumination, basically smaller versions of usually found
on horse box arches.

then trawling ebay noticed amber led units which could be mounted
on side skirts, big truck/trailer style.

other thought was reflective tape as seen on some box trailers around
the edge of the rear face of van and maybe yellow along sides.

any thoughts. did see a pack of 8 amber leds thought 4 for caravan
and others on side steps of troll...
