JimT Posted May 31, 2015 Share Posted May 31, 2015 Have just replaced regular lights with LEDS on trailer. Have also rewired/newplug trailer and new socket/trimmed wiring on 80 Series L/cruiser. Initially test fitted on Camry and all lights operating correctly.....but on L/Cruiser all but indicators working correctly....indicators very dull, however, once engine is switched on all good. So it seems that voltage is too low when engine off to run indicators....could it have something to do with excess voltage drop through flasher can? any help would be good. Thanks Jim Link to comment Share on other sites More sharing options...
batfishing Posted May 31, 2015 Share Posted May 31, 2015 I presume the lights on the land cruiser itself are working correctly? If so, check the wiring on the L/C trailer plug, and connections to the L/C wiring. The LEDs will run down to 9V without an issue, so would not suspect a voltage drop Sent from my iPad using Tapatalk Link to comment Share on other sites More sharing options...
locodave Posted June 2, 2015 Share Posted June 2, 2015 And if you run this on the camry, does it work normal? Link to comment Share on other sites More sharing options...
JimT Posted June 3, 2015 Author Share Posted June 3, 2015 (edited) every is fine when plugged into Camry.......all but indicators are fine on Landcruiser with motor off, once motor is started , indicators are fine as well........all lights on vehicles are fine as well Edited June 3, 2015 by jot Link to comment Share on other sites More sharing options...
The Incredible Hull Posted June 3, 2015 Share Posted June 3, 2015 Do you have a multimeter? Check your battery voltage with the car off. Check on both cars to see if there's a difference. Link to comment Share on other sites More sharing options...
antonywardle Posted June 3, 2015 Share Posted June 3, 2015 (edited) I had a slightly similer problem with my lights. The right hand indicator would work on some cars and not others. Turns out that for me, the problem was the female plug on my car was slightly too far open. After I closed it a little, it was all good. Yours might be the negative/earth Edited June 3, 2015 by antonywardle Link to comment Share on other sites More sharing options...
locodave Posted June 4, 2015 Share Posted June 4, 2015 Well obviously is the landcruiser. Follow the wires from the plug on the Landcruiser and see where it meets the wiring loom of the car. A wire there might be loose. I got mine done professionally and got similar problem like you. One of the wires was loose. These guys don't solder the wires, they just strip them and join them or use some crappy connectors. Link to comment Share on other sites More sharing options...

Yarraone Posted June 6, 2015 Share Posted June 6, 2015 you need to upgrade your flasher can/relay to a LED relay/flasher. without this they can also flash faster Link to comment Share on other sites More sharing options...
batfishing Posted June 6, 2015 Share Posted June 6, 2015 you need to upgrade your flasher can/relay to a LED relay/flasher. without this they can also flash fasterYou only need to do this if you replace the rear lights on the vehicle, as when you remove the rear lights on the vehicle and replace with LEDs, it reduces the Wattage Load on the flasher can. Old style flasher cans measured resistance, a drop in resistance means a globe had blown, hence the flashers flash quicker to advise the driver that a globe has blown.Trailer lights do not affect this. Also if replacing rear lights to LED, common on trucks, tray tops etc, you should purchase a pair of load resistors for the indicator system and wire in at the same Tim you connect the new LED lights, quicker and cheaper than a new flasher can. And on the shelf at Roadrunner. Trailer lights alone do NOT affect this, as you are placing extra load on the vehicle circuit not less Sent from my iPad using Tapatalk Link to comment Share on other sites More sharing options...
JimT Posted June 7, 2015 Author Share Posted June 7, 2015 Give us an update being a replacement Kaymar rear bar the loom runs thru the box section.....looks like need to remove whole bar to get access to loom......ain't going to happen....might have to "create" a new loom from the vehicles rear lights Jim Link to comment Share on other sites More sharing options...
Davemmm Posted June 8, 2015 Share Posted June 8, 2015 I would start with the socket on the landcruiser. Sometimes a simple spray with an electrical contact cleaner will give a better connection and make them work perfect. Dave Link to comment Share on other sites More sharing options...
Commodore Posted June 28, 2015 Share Posted June 28, 2015 Dave mm is on the spot. Start your troubleshooting by dealing with the simple and then move onto the more complex. Works more often than not. Link to comment Share on other sites More sharing options...
