Log #7 - Lighting System Renewal and Project Update

Renewing the Lighting System

In the previous log, the electrical wiring fault had been repaired and the decision had been made to completely abandon the fan-cooled LED bulbs used on the vehicle.

After the electrical system became reliable again, the newly ordered bulbs were installed and the front lighting system was fully renewed. The main aim of this work was to increase reliability while achieving a more balanced and higher-quality lighting output.

Removing the Old Lighting Setup

The first step was to completely remove the fan-cooled LED low beam bulbs from the system.

Before installation, the headlight sockets and electrical connections were checked again. Since no abnormality was found in the wiring, the new bulbs were installed.

This fully ended the LED conversion that had been applied by the previous owner.

Installing the New Bulbs

The following bulbs were used in this stage:

• Bosch Xenon Blue H7 halogen for the low beams
• Bosch Xenon Blue H1 halogen for the high beams
• Philips WhiteVision Ultra W5W for the front position lights

After installation, all lighting functions were checked one by one.

Checked systems:

• Low beams
• High beams
• Flash-to-pass
• Front position lights

All systems were confirmed to work correctly.

First Impressions

With the new bulbs installed, the overall appearance of the front lighting changed noticeably.

The Bosch Xenon Blue bulbs provide a whiter and cleaner light character than standard halogen bulbs while still keeping a natural look. The Philips WhiteVision Ultra position lights also match the low beams more closely, making the front lighting look more consistent.

After the wiring repair, no fuse problem or electrical fault appeared during the checks.

Based on the first evaluation, the intended result was achieved both visually and in terms of system reliability.

Project Update

After renewing the lighting system, I also decided to improve the maintenance and diagnostic equipment used in the restoration process.

Although I had previously used the foam systems at fuel stations during regular washes, the foam density and cleaning performance did not meet my expectations. To get more controlled and higher-quality results in future maintenance work, new equipment was ordered.

Products ordered:

• Polham 2-litre pressurised foam sprayer
• ValetPRO Snow Foam Combo intensive wash foam, 1 litre

The following tool was also added to the project so that electrical checks can be carried out more accurately:

• UNI-T UT33C+ digital multimeter

These items will start being used in the next log, where the first-use experience will be documented in detail.

Conclusion

With this work, the front lighting system was fully renewed and the system was confirmed to work correctly after the electrical repair.

The new bulbs created a more balanced colour match in the front lighting while the electrical system continued to operate reliably.

With the newly ordered maintenance and diagnostic equipment, the project is not only progressing through work directly on the car; the infrastructure for future maintenance and technical checks is also being strengthened.
