I've recently purchased a Heljan 3340 with 'Howes Sound Fitted' (possibly a LokSound V3.5?) from an auction site.
I see that the directional lights are not LEDs, but bulbs, so I'm guessing this particular model hasn't been manufactured for quite some time?
This is my first Heljan purchase, so not sure if this is a common issue with this manufacturer, but does anyone know of a guide that might exist on how to upgrade this model (or all 'old' Heljans) to LEDs?
Thank you
