HST headlight redesign

[Wapps]

To me, the redesign is a functional improvement on a piece of safety equipment that allows safer use of the vehicle. If aesthetics are allowed to drive safety considerations on a public transport system, the the lunatics certainly have taken over the asylum!

You present it as binary - safety or a great design. I suspect it is possible to do both.

Indeed - the new design is both safer and better-looking.

It also makes the service more reliable. On Midland Mainline the savings from delays due to erroneous “no taillight” reports (the lights being much dimmer than their replacements) more than justified the cost of the new lights.

Presumably the new design benefits from the exemption from a yellow front/rear cab face, as the BLue Pullman set is all blue and white on the front.

Very true!

The new headlights comply with the current LOC&PAS TSI requirements and so yes, they do allow the omission of the yellow warning panel, but only if a high-level marker light is also provided.

Correct. I believe one of the conditions of no warning panel is a cyclops light.

I'm not entirely sure the "new" (MTU re-engineering era) lights are compliant. The blue Pullman Powercars have got the later LED headlights (they have a tell-tale 'triangular' shape) & revised LED markers as fitted to 700s and 800s (eg), whilst those first redesigned lights have got the HID headlamps & LED markers that were retrofitted to a lot of BR era stock (often replacing the old 3 segment lamps with the vertical bar markers)

The fact that the pullman cars were upgraded from the Midland Mainline 3-segment design with incandescent bulbs complicates this as they had to go to the latest offering, but if they meet the necessary specifications in terms of light intensity, direction, size and functionality (per EN 15153) then they would allow for removing the warning panel. It'll be interesting to see what happens with the H&H power cars, as they've been repainted without yellow panel or high-level marker light. It's gone quiet, but some flick searching shows 43480 with lights removed, so watch that space!

Yeah I was unclear, sorry, I meant the very newest sets for the purpose of TSI compliance.
