led lights on a jayco sterling 2009 model are they 24 volt compatible

G'day Scott
Probably not something most have looked at or even considered.
If you undo/ flick out the light unit on the van you will see in the back a white printing which may say 12/24v. If it has that, then the internal circuitry detects when the voltage goes over the normal slightly higher than 14.5to 15v and it then dulls all lights which are on and they gradually get brighter as the voltage rises to the level used in a 24v system.

If you can't get to the lights then switch on the parkers and note the brightness.
Remove plug from towbar and use a normal plain old battery charger connected across pin 3 and pin 7. Only the correct way will light the lights though as they are LED ie one way electrical valves.

Since a plain battery charger gives out about 16 to 17v dc it will light the lights but they will go into the dull phase. If they go dull it is a 24v compatible LED lamp. In not 24v compatible the LEDS will be brighter with no dulling observed.

As far as I know all LED lights are 12/24v compatible. If you are not sure check the Narva or Hella site online.

There are other things to consider as well such as running the 12v fridge on 24v while travelling also the 12v charging system while travelling.

Hi Scott,
On a separate matter, you may be interested to know that you can run 12 volts from your 24 volt truck to the caravan if you want to have internal lights etc. you just need to run a positive and negative wire from only one of the batteries. Use the second battery that is connected to the earth. You can easily test the voltage with a multimeter and truck running before you try it, if your unsure if it’s true.
