Looks like you got a TJM bar John.
If so, and you have those annoying to get out lens covers, just get a pair of LEDs off ebay to replace the globes.
I just did mine, actually had to get two new indicator units as the globe bayonets were rusted madly in mine($20 from TJM), then I installed the LED globes(any $1 LED globes will do the job nicely).
Amber coloured LEDs seem to 'work the best' behind those amber lens covers too.
Another thing you can get9if you want to change all your indicators to LED(which is what I did in the end) .. is to get an adjustable indicator relay.
The unit is designed for the defender, but nearly fits the disco perfectly.
By that I mean that the pin cofigs are the same(4pin) but the shape of the relay body is different. So I made up 4 spade ended hook up wires, connected the pins to the appropriate slots via the wires and cable tied the relay up into the fuse box area.
The relay itself has a small trimpot that allows you to adjust to whatever point where your trailer indicator doesn't come on. So when you do connect the trailer, it then comes on.
I got a whole bunch of LEDs to try out(packs of ten) and used
THESE (cheaper) for the bullbar replacements and
THIS type (bit more expensive) for the car replacements.
Note that I didn't purchase those exact globes form those sellers, I got mine from either China or HK cheaper(about $10 for 10 or something) .. and in mixed colours(red, white and amber).
Like I said before tho tried the whites and they bleach out the orangey colour of the lens, so used the amber coloured there.
