1.3.3 Replacing traffic light lamps
In the current production of the AS x70i DUO, LEDs are used for
the traffic light. These LED lamps are maintenance free. Older
versions of the AS x70i DUO use festoon bulbs. The replacing of
the bulbs is described below.
To ensure water tightness after replacing the lamp(s), the screw
washers should be replaced with O-rings.
SKIDATA™ article code for O-rings: AS 350 ZA,
No. 535200020
 Make sure the lamps are positioned tightly in the lamp holder
(press the contact plates of the lamp holder inwards as nec-
essary)
 When re-assembling the traffic light, ensure precise position-
ing of the sealing washers.
 Be careful not to fasten the screws too tightly.
