Single LED power consumption

Well today’s project went well, then I realised the USB sockets have an LED permanently lit! Can anyone tell me how to work out the power consumption for it? Wondering whether to put them on a switch or if it won’t be any worse than the immobiliser LED

Have similar USB/ ciggie lighters 6 of them in total...never worried about it and the landy starts after a few weeks of doing naff all, but it is a 300tdi so is proper like...LOL .

Cheers

Hey, I resemble that.......I got an alternative thingies on it and one of those startythingamyjobs......Plus me candles on the front and rear....

Cheers

I have a 300tdi in an off roader it’s a pleasure to work on compared to the newer engines

I had one of those annoying little lights on a switch for my spot lights, I was as worried as you! I ended up wiring the switch through the headunit signal cable just to be sure. So made it a switched live.

TBH, it probably would not hurt to put a switch on mine, but not on my priority list.

I thought about that and while everything’s still out from installing a flip out radio Bluetooth satnav thing I might well do it

I have done the same for my EGT readout, does mean I have to have the lights on to read the EGT tho...

Leaving it perm live.Only real risk i see, is if you leave something plugged in , such as a CB for a few weeks.....................

Not sure if there is an ignition live in the rear, I don’t think there is

Wire one in!

There’s only so much you can take off the cigar lighter!

Thats why I said use the signal feed for the head unit, can wire that to a relay and so forth. Lil long winded and annoying I know. Though its exactly why I chose unlit 12vs, ive got 5 in my 110 all perm lives.

My cigar lighter powers itself, the radio aerial/GPS and two usbs between the rear wash and cigar lighter. The other stuff I’ve added is permanent live on a separate fuse box from the battery, things like the rear spots, beacon, interior lighting. All low power stuff (LED). While I’ve got everything hanging out I could sort out an ignition feed off the radio for the future. One thing that will definitely want it is the tracker which has been sat in its box for a year!

Yep, this is what I've done too, signal feed from head unit to a relay in the back that has a live feed direct from the battery. The only downside now is that I can't use the sockets in the back unless I have the head unit on, and I mean really on, not just power to it from ignition.

Considered changing the relay trigger to the ignition feed, but then I'll just be moaning that I have to have the keys in and turned to use the sockets...

So, I'm going to add in a 3 way switch that can be a relay override option.

Of course, at some point I'll leave it on and zap the battery overnight.
