1. Carefully prying with a screwdriver, remove the cover from the lamp assembly.
2. Press the lamp, turn it counterclockwise and remove it from the socket (see accompanying illustration).
3. Installation is carried out in the reverse order. Check the cartridge for corrosion and install a new lamp that matches the one removed in terms of operating parameters (see tables of sizes and adjustments at the end of the guide).
4. Replace the cover.
