On the 707’s the headlight stays on one setting regardless of Day or Night.
So when did the idea of a day headlight on the non-driver's side become the custom?
I asked this question of a Pacer driver in the early 1990s and he seemed to think that the non-drivers side headlight would dazzle oncoming drivers at any time which is why on stock of that era (Pacers/Sprinters/Networkers etc) which had tail/marker/headlight clusters fitted on both sides, in BR days only the drivers side headlight seemed to be in use'Night' headlights face away from the Driver side as is won't dazzle the oncoming Driver
There’s no set times in the rules/ company instructions, it’s down to the Driver.With regards of Day & Night running lights what are the rules regarding when switching from one to another. i.e. is there a set time depending on time of year also why do HST locos have the ability to have both sides on?
Not true AFAIK....Right is daytime and left is day nighttime...If you check on the 455/456/458s running about generally they will abide to these rules unless headlight failure…(oh and desiro...even says it on the headlamp switch.)On SWR 455, 458, 450,444 it’s driver discretion when to change from Day/Night Night/Day.

Not too sure what your trying to say. As I said in my post it’s the driver that decides when to switch over to the Night Headlight, usually about dusk as there is no Rule Book ruling on this and the same for going back to Day Headlight about sunrise time.Not true AFAIK....Right is daytime and left is day nighttime...If you check on the 455/456/458s running about generally they will abide to these rules unless headlight failure…(oh and desiro...even says it on the headlamp switch.)
158/159 same.
707 have three settings....Nighttime/Daytime and marker lights...In the olden days on the 442s these rules never seemed to apply (and I never seemed to get it right) and 455/7s and 455/8s and /9s either didn't have a right side headlamp or it didn't work.AFAIR.
As Commuter said I think the nighttime setting on 707's may be more dipped.
I have looked at my photos of IET (all GWR) and they do run with with both headlight on.IETs seem to have just one setting (im probably wrong but this is just from seeing them), and that is all 4 lights plus the high level marker on in the direction of travel
Surely if there are two different intensity of lights fitted, the brighter light is needed during the day so that the train can be seen by others?
Yet another issue apparently arising from privatisation and the concommitant fragmentation - where is the national standard on headlights? Why are different TOCs seemingly free to do what they like? The same applies to destination indicators on units - another lottery as to whether they can be read in daylight or not.I want to highlight this thread to TPE. Their trains are awful in the dark. Their headlight setting must be either “off” or “harvest power from passing galaxies”.
