I can't think of any reason to install an LED in the license plate light. If it wasn't required by law I wouldn't even care if it wasn't illuminated at all. I can't imagine spending the money, even $5, and the time to swap it to LED.
Tail lights maybe, but only if the indicators are swapped too. I have my doubts that an incandescent indicator could be seen well next to an LED tail light in some conditions.

On the other hand, a woman in high heels is a turn of for me, so it's no wonder I don't get why people do a lot of the stuff they do.

I dont have bulbs for my licence plate holder, they are burnt out and we dont have inspections and I'm not going to replace them.

And here is another reason not to have LED tail lamps.



They dont get hot so they dont melt snow.

 

Ha!. No. Hiking boots are way sexier than high heels. Even Sorel Caribou boots are sexier, in the winter.

 

With all of the unused switch positions available on a Disco, there's plenty to add the "LED light defroster switch".

It just switches on the regular light bulbs.

 

Why would that be an issues, most states have laws where you're supposed to keep all lamps clean - just like you're supposed to make sure you can see out of your windows. Do you just get into a truck and start it up and not clear your lamps?

 

I've been stopped twice here in Arkansas for not having my liscense plate lit up. The first time they were burned out. The second time there was so much dirt under the lense you couldn't see the light.

Anyways the money for the led's is a waste. I've had friends argue that it's worth it because they last forever, but the lights lasting forever is the least of my worries on my rovers.

 

This.

In a heavy enough snowstorm, I have to scrape my headlights because regardless of the fact that they're on, they quickly become occluded with ice to the point where I can't see **** because the ice is diffusing the beam making seeing through the snow impossible. Before I hit the road, or get back on the road at a gas station or rest area, I always check to make sure that all of my lights are clear of snow and ice. Relying on lamp heat isn't always a winning proposition.

Furthermore, turn signals, reverse, and brake lights aren't exactly running lights, and as such will become occluded just the same as an LED light would, because there's no heat when they're not on. Which makes the whole incandescent = snow melting heat argument null.

 

I'm pretty sure Spike was talking about snow blow back while you're driving covering the lens again after you've cleaned them off before you start out. With incandescent at least it take a bit longer to get covered again and at least your tail lights can be seen, as opposed to everything soon being covered.
But even so, forgetting about that, other than for a rear fog light I think LED's are just a waste of money unless your reason is the coolness factor. I can't think of any practical reason to switch to them. But I'm open to being educated on why they worth the price premium.

For a new install, yes, they could make sense because you can run smaller wires to them, on the other had the premium price for the lamp probably is more than the cost of a gauge or two increase in wire size.
I can see them maybe for driving lights, or headlights on a Series, Defender, RRC. Or for vehicles with small hard to see lights, like a Series.

I tried halogen bulbs in the rear bumper lights on my '95 Disco but the heat melted the lens.
I'll just use them in my Air Portable because it has glass lenses, and small ones at that.

 

It was covered in another thread, but the illumination time from switch closure to full brightness of an incandescent is far, far slower than a LED, as much as 0.3 seconds.

At 65MPH, a 0.3s quicker response time translates to over 20 feet. That can mean the difference between a close call and stopping in someone's back seat.

*edit*
0.3s at 65MPH is actually over 30 feet. The length of a small truck.
