Cab Top Marker Lights

[wheel_nut]

Here is the page from manual that the VOSA testers use.

Skeletal trailers with containers do no need top lamps. Obviously

Nor do demountables, or tippers and tankers

What happens if you pull a container they don’t have top marker lights on them. You then
only have 4 marker lights and 2 headlights.
Why do they have lights on top of trailers any way

Skellys have two on each side at the bottom if they were built after 1999, as do low loaders and flats.

Which in fact is the top on those sort of trailers.

Since you ask, a container isn’t a trailer, its a load.
Second question, so you can see where they are in the dark.
Third question, that you didn’t ask, cab top lights are to show that it’s a big vehicle
even when it’s too dark to see the rest of it.

Ive learned something new today about a container.

It’s why many years ago before they changed the road tax system and it was done on number of axles you were supposed to drop the axle when running with an empty container as it was the load.

‘Old-school’ tilts used to (still do?) have 2x marker lamps each side, as there is nothing to fix them to at the ‘top’
As I recall, cab-top marker lamps were made compulsory circa 1983 (‘Y’ to ‘A’ reg)

How comes the ‘top’ markers on a topline scanny are on the visor and not the roof?

Our 3 brand new mega trailers don’t have top markers front or back.
