Step 1: Preparing the Tail Light Housing

The first step involved removing the existing lens from the housing. I heated the unit to soften the butyl seal and carefully pried the two apart. Once separated, I marked and cut the housing to accommodate the new LED setup, ensuring not to compromise its structural integrity.

Step 2: Making the New Lens

Crafting the new lens required heating a piece of red acrylic until it became pliable, then shaping it over the old lens to retain the correct form. Precision was key in cutting out the new lens and ensuring a snug fit on the housing.

Step 3: Bonding the New and Old Lens

With the new lens shaped, I sanded and cleaned both it and the old lens's edges to prepare them for bonding. CA glue secured them together, and I used adhesive sealant to ensure a watertight seal.

Step 4: Designing the LED Panel

Next, I focused on the LED diffuser panel. I made a template of the housing interior to cut a clear acrylic piece, which I then frosted and shaped to fit inside the housing snugly. The design for the LEDs was cut from vinyl and applied to the diffuser to guide where the LEDs would sit.

Step 5: Assembling the LED Channels

I measured and cut roof flashing to make channels for each LED strip, ensuring separate sections for different light functions (brake, turn, reverse). After testing the LEDs, they were secured onto the diffuser panel, and I meticulously wired them, paying attention to polarity and connecting them to the car's light functions.

Step 6: Sealing and Finishing Touches

Finally, the LED assembly was placed inside the housing and sealed. I carefully reattached the modified lens to the housing, using butyl to ensure a firm seal. After reassembly, I tested the lights thoroughly to confirm proper operation.

Conclusion: A DIY Success

Though not a process for the faint-hearted, upgrading my Honda Beat's tail lights to LEDs was incredibly rewarding. It illuminated not just the car but also my ability to tackle such a detailed project. The result? A unique blend of old and new, making my Honda Beat stand out even more.
