Outside LED lights - AC or DC

I'm looking at installing LED lights on the outside of my trailer. Different lights on the side and back to help light things up. Should I go AC or DC?

Pros/Cons
AC - can use when on battery i.e. backing up
DC - doesn't drain the battery, probably easier hookup since I don't have to run a wire from the tongue to the back

Thoughts?

I got my AC/DC backwards, but you understand the question. Battery vs. Plugged In.

TIA

Why go with AC when you can install DC and use either when boon-docked or on shore power? DC would be what I would go with.

I'd go with DC, but for a different reason. All LED's are DC so to make them run off AC power you have to have a transformer and rectifier. Why add more parts to the mix when you can just go with DC to begin with and reduce some failure points.

Just be sure to buy units that can stand 14+ volts as some units have a very narrow voltage range.

Majority rules! DC. There is extremely low power drain with LED. If you haven't switched the interior lights to LED, might be a good thought as well.

Not all leds are DC, but 95% are.

You do have a choice all outside lighting is 12 volt dc, no matter if it is a brake light or a coach light, now the only time this will change is if you add some kind of 120 volt outdoor lighting, but if it is factory all your lighting inside and out is 12 volt dc.

Hope this helps and Happy Camping and also since you are looking to replace all the outdoor lighting you might want to think of indoor also and you can get all of it here with a huge savings (LED light bulb, LED light bulbs for home use and cars) and get them DIRECT and save big money!

DC also. I just replace all the outside lights on my 2004 5er with Led. Even replaced both scare lights which are Led. Purchased from EBay.
