well .. as for the strip leds .. i'd probably chance these ..
http://www.autobulbsdirect.co.uk/Flexi-Day-Light-Running-Strips-NEW.html
as products ( filament bulbs and leds ) i've bought from them have all performed well
the specs do state "weather proof" ..
and if the adhesive be like the double sided stuff used for reg. plates then it should be ok
i.e. if the surface properly prepared / cleaned ..
~~~~~~~~~
i use multi-led side lamps ( with led tail lamps ) in leu of DRLs
and if more DRL illumination is needed .. i've led fog lamps .. not as bright/glaring as filament types ..
all in all .. less work for the alternator / battery ..
and .. at the moment .. i don't hardly ever drive at night .. so the heat from filament headlights
aint going to kill off the led side lamps in a hurry
~~~~~~~~~~
as for fog .. in 28 yrs living here have hardly encountered any .. well not enough to warrant fog lights
and should i encounter fog .. i could always angle the headlights at full-down position ..
as my hippo never gets loaded much on the rear ..
( as is .. i angle them down by 1 notch for 'normal' use .. unladen commercial ..
( full height only on virtually traffic free roads after dark ..
and if snow were to cover my tail lamps 'n not melt for lack of heat from the leds
i'd stop 'n clean them .. or use the filament rear fog tail lights ..
or refit the filament tail lamps ..
( depending on the situation .. have yet to encounter That much snow here ..
( or done .. or planning to do .. extended snow laden journey time ..
