I found some good looking rear red LED lights that can be powered off 12s battery voltage.
This one even has turn signals! 
They’re pretty expensive from this seller though.

Hm that’s cool I haven’t seen that one before
If you put strips of reflector tape on those motors, you’ll get a pulsating effect while you’re moving. I saw a video clip somewhere long ago but couldn’t find it again.
The reflector tape peels off and makes a flapping noise eventually, and then breaks off in pieces.
Ask me how I know
Typically not if you use edge sealer correctly.
I wonder how hard it would be to get those indicators to be switchable off a handheld remote, looks way more robust than the other current indicator light options and battery voltage is mint

Anyone here seen anyone mount a laser light to their board? Similar to the Lorentz Major.
Hypothetically, let’s say I have space for a buck converter, and I want to wire 2 laser diodes to my enclosure. I have 2 3-5V laser diodes and a 72V buck converter (using 16s battery).
The diodes run off a small amount of current and, for this application, would need the lowest voltage operable in order to run for a long while. I doubt I could wire in a physical switch, so I may need to run it off the BMS/Battery. I’ve seen diagrams of buck converters running off BMS with a loop key, but just wanted to know if the same method will work with a power switch?

Please let us know how it is. Looks interesting!

I’ve been wanting to do this for a long time, motorcycles and esk8 have the same problem in that they are too narrow and when they are behind a car in traffic they disappear in between the car ahead tail lights and people often don’t see them because they are looking for car tail lights that are multiple feet wide and lights on motorcycles and esk8 at a couple inches apart. If you could project a very wide bright pattern onto the ground behind you I think it would help a lot and it doesn’t take very much space to put a projector like this on a board.

Problem with a lot of these lasers is that their run time isn’t very long according to the reviews. Seems like you have to either run it at the lowest operable voltage, or limit the current with a resistor. Quite surprised noones installed these before. Might have to ask how Lorentz wired theirs up.
patterns are also available
all my esk8 lights are 12V via step down converter
I found cheapest way for rear lights too

Voltage: 8V-36V (12-24V Recommended, otherwise the lighting effects will be affected)

Can you show me how you’ve wired these to your battery? I may need to find a way to hook these up from the BMS and power switch for mine. I could also wire in a switch but I’d rather have it automatically be in, despite the battery drain risks.

I might look into using a push-button switch. I just wish there were buck converters that were a bit smaller. Would be easier to work out spacing within an enclosure, especially with an added switch.
There are smaller converters on the Ali, but they have a plastic box. I choose Aluminium case because of EMC.
From my experience are rocker switches more robust then push button.
