Looks like you live here in Canada, Alberta. You get some nasty winters out there.
Have you ever used LED lights on the exterior of a vehicle before?
I'm not a fan of them.
They don't produce enough heat to keep the head and most importantly, the tail lights clear in a good snow. Visibility is good.
Yes, you clear off your vehicle before you start out, but any Canadian knows that it doesn't take long for good snow build up to happen in a snow storm.
I've had several incidents in the last few years of almost hitting someone from behind because I couldn't see their brake lights, or any lights. It's always been a car with LED lighting. My wife's new Subaru last winter, Halogen headlights kept the road clear ahead of her, but zero could been seen of her led taillights. A 10 minute drive home from school and nothing could be seen of her tail lights. I am currently trying to figure out how to retrofit them back to a good old, heat producing incandescent bulb.
In snowy winter conditions, I just don't think they're safe.
I drive my vehicles all across Canada for work. On the road, I've seen it all.
All this negative being said however, LED's do make great supplementary lightning, I have have LED light bars or driving lights on all 3 of my vehicles (just put them on the ST yesterday) and love them. I couldn't imagine allot of dark nights in the middle of nowhere driving without them. I am know they have saved me from hitting more than a few big animals on dark nights.
Just my 2 cents worth, food for thought.
