Rear position lamps

[conker]

I have a Vauxhall Corsa in for test next week
And I noticed he has sprayed is rear lamps
A dark colour
What justifies a failure

[dwain]

Judgement call on the light emitted being intense enough and/or still red

And don't forget, product on lens.

There may be a fail there if the reflectors are incorporated within the lamp ,did an Astra recently,light from the tail /stop lamp output was ok but no reflectors.

Wrong colour!

Just a side note to tail lamps!

If a vehicle fails for a tail lamp inoperative because only one on each side of the vehicle is fitted, at the rear, would you consider that a dangerous defect and why?

"Position lamp has a product on the lens or light source which significantly reduces light intensity"

re. original question; Even if you can still see the sidelights, reflectors seem to completely stop working once sprayed assuming they are in the same lamp

I could have swore it covers it, 4.2.3 b i and ii. in the lighting department.

[nitros44]

4.2.3 (b) ( ii)
Under product on lens ,but needs to effect intensity for major fail

What's a tail lamp ?

Don't know but must exist according to the manufacturers...




Look at the image lowest horizontal column, to the left, it says tail lamps. 

[nitros44]

That's all well n good Dave but we're in the inspection manual are they ??

postion lamps

I think there has been a lot of misunderstanding with the use of words and terms with regards lighting systems over the years. there used to be a time when we called the lamps "side lamps", and I remember talking about this to a VE saying that these lamps are not side lamps, which would be interpreted as fitted to each side of a vehicle, and not the front. The wording used in the past, and still used today by some is tail lamps. These are rear position lamps, but by saying tail lamps, anyone should pick up that they are at the rear. Now position lamps we know are nothing more than a 501 bulb in most cases, but I've had customers in times past who have been to dealers with these position lamps not working, and the dealer have sold the customer a new headlamp. When I asked why the new headlamp was purchased, I was advised the dealer said that is what a position lamp was! Without a definitive industry agreed terminolgy then the customers will get the short straw most of the time. 

Tail lamps are the position lamps fitted to the rear of a vehicle, but to distinguish between front and rear, some manufactures as I posted still use the terminology tail lamps.

I would have thought we would all recognise the term 'tail lamp' as a rear position lamp.

Not quite everyone on this thread. Some of us are as old as Noah's Ark
