We are slowly replacing the weaker bulb lights with brighter LED lights (below) – after this lot, only the headlights are left.

• Interior lights (MUD UK) – these were easy to fit and an instant improvement over the originals. One neat aspect is that you can choose between white or red illumination (for night time).
• Side indicator lights (Nakatanenga)
• Fog and reverse lights (MUD UK) – as usual, the original lamp fixtures were very corroded! We ended up removing the plastic box with a Dremel cutting disc and hole cutting drill bit, then sawing the remaining bolt in half. Any slight damage to the underlying metal was covered by the installation of the circular 95mm NAS plinth (part number LR009773). This is meant to be fixed using a hexagonal bolt held in the captive hole of the plinth, but we found getting a spanner on the nut from behind the back panel very tricky. In the end, we opted for securing it with self tapping screws. The bare wires were terminated with a female econoseal connector (using the crimping tool shown). Finally the lamp was connected up and screwed into the plinth.
