When I cut the strip is the rest usable? Does it come with power supply?

Thanks for your questions. If the 16.4ft/5m is too long, please choose the best length to cut the LED Strip Lights. The LED Strip Lights Kit has 1pc power supply. JunWen Customers Service Team

After I cut the strip, what do i need to buy in order to use the left over lights? What type of power source do I buy?

You can get power adapters in multi packs. I bought a 10pk not too long ago for around $7.00. They make strip connectors that clamp onto the cut ends and also strip adapter with short wires soldered to them on one end as well that can be used with an adapter to connect to the power supply. As long as you buy 12 volt DC power adapters, you will be good to go on the cut ends.

I will be using these for my camper van. Can I eliminate 12v adapter and directly hook to my car battery(12v)?

Glad to get your question Yes, you can use 12v adapter directly, but please make sure it`s 12V. JunWen Customer Service Team

How wide is the strip lighting? 1/4” would be perfect

Yes it’s 1/4 inch and it works great and very bright and easy to install
