Swapped all the bulbs for LED lamps on the ZX. Indicators, stoplamps, reverse lamps, side lights and headlights. So much brighter. Used warm white for side lights and headlights, they retain the softer filament bulb type hue to the light but so much more light output.
Didn’t need to swap the relay for the hazards , they blink normally. Had to swap the relay for indicators to stop them flashing too quickly. Swapped it for an electronic relay but still has the clicking sound. Couple of cheapie relays I tried off eBay didn’t click.
Also swapped the cabin lights for LED bulbs, but going to retain the filament bulbs for the instruments as the coloured LEDs I found too harsh on my old eyes.
Great company I got them from, huge range. I would definitely recommend them for the prices and customer service .
