I love LED lights.
They are more durable, and have a much better and higher output of light, compared to the old incandescent bulbs.
And if there is a bad connection or earth wire, it has to be almost disconnected before it affects the light output, as the voltage to run a LED light often is anything between 6-32V
But the design of most of the LED lamps are very modern, and unfitting for a 50+ year old vehicle like Laura.
Luckily there is an option of mounting LED bulbs as well, witch is the way I plan to go.
Philips have created a series of bulbs that they call Philips X-tremeUltinon LED. They have H4 bulbs that I upgraded Laura to, back in 1992
Complete headlikes like Grotes 7″ units are a possibility, but maybe a tad modern for an old Land Rover.
Marking lights, indicators and rear lights
These are an easy upgrade.
The largest challenge is swapping the original bi-metal blink relay with an electronic one, as the original would blink too fast with the low consumption of the new LED models.
The bulb can be exchanged for a LED unit. But there are a lot of third party replicas with a LED light in, that can be mounted instead of the original lamp.
The original light in a series Land Rover is a simple but very dull lamp.
It can be upgraded with a new LED bulb, or swapped out with a LED strip.
Engine compartment illumination
Not a standard feature, but a very practical upgrade.
There are a lot of watertight options for 12v
