Thanks for the replies,
Yes - Checked it out on DC both before and afterwards and all is fine there with the Lights.
After going back to DCC I then had one of "those" moments....... "Ah, If I had been looking at the bonnet end as well as the cab......." Yes, you guessed it, I had tunnel vision on the cab and didnt notice the lights coming on at the Bonnet end!
Anyway, this is what I found.
F0 = Bonnet Marker light
F1 = bonnet Red light
F2 = Cab Red light
F5 = bonnet Head Light
F6 = Cab Head light
It appears the only one I am missing is the Cab Marker light
RE the Chip I have - Lok Pilot 5 DCC/MM/SX/M4
At the time I bought 134 I didnt have the money for the sound chip and I thought I would do something later - "Just make sure not to miss getting one of the Locos!"
A sense of technical curiosity now has me wondering how I can find where the Marker lights Joe, do you have a reference for this -"Unless you have DCC knowledge of Mapping functions using the Lok programming / Decoder Pro with a Sprogg"? I mostly use Hornby Railmaster for Programming my Decoders and I have a Roco z1 controlled either by a MultiMaus or from surplus iPad. I have also used one of the Free Dcc Programming tools previously that could pick up the z1 - I dont have the Train laptop to hand say which one.
On the other hand, part of the sound track of my childhood was listening to various GM Locos going through their scales while they sat in Kent station waiting their next duty -My Father used to pick up Packages from FastTrack many an evening and I would go along and wander along the platforms until the paperwork was sorted. there was inevitably one or more GM engined leviathan ( to me) sitting there with its engine note going up and down, or perhaps hauling something through the station. So maybe I should go for the sound chip for 134 - She's certainly the most characterful Loco I have.
Cheerio all.
