the parking lamp is in the headlamp unit the bulbholder

The bulb is secured by a bayonet coupling.
Number plate lamp:
To replace the bayonet coupled 5W bulb remove the

Lamps give insufficient light:
Test the state of charge of the battery and recharge if it
is necessary from an independent supply. Check the
setting of the lamps. If the bulbs have darkened through
age fit new ones.
Lamps burn out frequently:
If this is accompanied by a need for frequent topping-
up of the battery and high hydrometer readings, check
the charging rate with an ammeter when the car is
running. This should be around 3 to 4 amps. A reading in
excess of this calls for adjustment of the regulator.
