Yep - as a new driver they were just starting to install those in all the trailers where I worked in '03, so some had traditional lights, but the rest LED. I got to experience that problem first hand, seeing I got hired in the thick of winter.
Hell of a way to learn to drive. Set of doubles, on an unplowed major highway at 05:30 after working all night long on a loading dock with a pallet jack (no forklift for the new guy ...) moving hundreds of tons of freight, tired, empty kite, 20k on the lead ... then watching the kite almost pass me after jacking brakes on after coming up on a plow in blinding snow!
I was instantly warm after that!!
Thank God there were no cars in either lane beside me. My driving career would've ended my first day! Though for sure I was done for. Good thing I screwed around with vehicles as a youngster. Had I stayed on the brakes like most people instinctively do, It would've been game over.
