Some advice please. I am renewing wiring on my boat. I have bought two new LED reading lamps for the forecabin and want to run a single two-core wire from the distribution panel to the forecabin, connecting the two lights in parallel. Can I use heat-shrink butt crimps to wire the two lights in parallel, with two wires coming out of one end and one wire from the other end? Like this:

Or should I use some other technique like automotive style terminal blocks? Would rather use proper butt crimps. Any advice please

Thanks
 
If I was using crimps I'd be looking at the wire diameters and maybe folding one double so that it's big enough to suit the crimp chosen for the larger (combined) wire size.

Yes, you can. With the glue lined heatshrink connectors you describe it is possible to make a good connection. Make sure that the insulation of the two wires goes fully into the connector.

You can also use the Wago connectors, as linked to in post #2, the 221 series are more compact than the 222. Often when i use these i stick them in place with some fast drying epoxy, they make a very neat, reusable connection.

Both methods are perfectly acceptable, so whatever you prefer. Please don't use chocolate block connectors :disgust:
 
You could just wire the second light into the connections on the first light if you have the room for the wires.

+1 the glue heat shrinks are great 12 volt planet or Amazon does a nice box of varying sizes and connectors , I have wired all my lights , led ,reading lights , ceiling lights like this , use a heat gun to seal then.
