Rear light bulbs

The rear lights of Skoda Fabia Mk4 cars can be 'all LEDs' or be a mix of LEDS and conventional bulbs.

This 2023 forum enquiry was about the latter type.

and (for right-hand-drive models) the 'mix' is as shown below, with the outer light-units having bulbs, while LEDs are used in the two number-plate light-units and (on the right side of the hatch) in the fog=light/reversing-light unit. The light-unit on the left side of the hatch is a dummy and has no LEDs in it.

Left-hand-drive models will have a LED fog=light/reversing-light unit on the left side of the hatch and the light-unit on the right side of the hatch will be a dummy. with no LEDs in it.

The bulb-changing guidance in the Fabia Owner's Manual is fairly good and the types of bulb involved are shown in the image below

Gaining access to the bulbs should be straightforward. Pull off the black plastic cover that's next to the light-unit; remove the two T25-head retaining screws; pull the light-unit straight backwards. There's a small plastic ball (purple ringed on the image) that engages with a small plastic socket in the bodywork and a small amount of force may be needed to get the ball to disengage. The Manual suggests that the light-unit be disconnected, but that should not be necessary just to change a bulb. I found that removing the P21W (brake light) and WY16W (indicator light) bulb-holders was easy, but removing the W5W (tail light) bulb-holder was fiddly. The P21W and W5W bulbs were OSRAM-marked and I assume that the amber WY16W bulb. was also an OSRAM product.
