Heinz57 Posted May 17, 2013 Share Posted May 17, 2013 Hi all, I have recently purched one of the Oxford Diecast low loaders. I was thinking about fitting working hazzard/warning lights to the top of the cab. Just wondering, what will be the best way to do this? Is there a ready made circuit avalible that would be suitable to use? (perhaps by just changing an LED colour to orange) Or have I got to make the circuit myself (in which case would someone know of a suitable circuit diagram?) I could run it off a 12v supply, however, that might limit me to only having it in one location. Perhaps running it off a button-battey type supply I could have it wherever I wanted it to be. Has anyone ever attempted this before? How easy or difficult would it be for me (someone who tends to be useless at this sort of thing) to do this modification? Cheers, Heinz Link to post Share on other sites More sharing options...
RMweb Premium Temeraire Posted May 17, 2013 RMweb Premium Share Posted May 17, 2013 Heinz Have a look at the video clip in post 715 of the Leaford thread, Kevin has added flashing hazards to a lorry using a DCC chip. I'm sure he'll fill in more details if you ask him nicely. http://www.rmweb.co.uk/community/index.php?/topic/4130-leaford-1990s-nse/page-29 Link to post Share on other sites More sharing options...
Suzie Posted May 18, 2013 Share Posted May 18, 2013 The signalist SC1 controller will do what you need for a fixed installation on AC, DC or DCC. It has eight outputs that can be individually configured for flashing lights, xenon flashers or rotating beacon which should cover most likely scenarios, You might need to find a friend to configure it with DecoderPro or another DCC programmer, or perhaps the supplier might be able to do it for you. Available here:- CR Signals CoastalDCC Just add LEDs and power. Link to post Share on other sites More sharing options...
Poor Old Bruce Posted May 19, 2013 Share Posted May 19, 2013 At Derby exhibition last weekend there was a trader selling just such flashing lights but I'm afraid I didn't take any more notice than that. If you can find the thread on the exhibition and see which traders were there, you may be able to find something useful. Link to post Share on other sites More sharing options...
cromptonnut Posted May 19, 2013 Share Posted May 19, 2013 Try http://www.expressmodels.co.uk/acatalog/Scenic_Effects.html Amber Flashing Lamps Ref: EX/AFL or Double Amber Flash Unit ( Universal) Ref: EX/AF2(B) may well suit what you're looking to achieve.

RJS1977 Posted May 19, 2013 Share Posted May 19, 2013 Alternatively have a word with Kytes Lights - they may be able to advise (and if they think it's a good idea they'll probably add a ready-converted model to their range!). Link to post Share on other sites More sharing options...
depot1 Posted May 19, 2013 Share Posted May 19, 2013 Have you considered using fibre optic cable? This would allow the lorry to be lit form a remote location like under the baseboard. one LED supplying all the light, rather than having to work the whole mechanism into the lorry.

This would allow the lorry to be lit form a remote location like under the baseboard. one LED supplying all the light, rather than having to work the whole mechanism into the lorry. I have successfully used this method before to have working lights in N gauge vehicles so there's no reason why it shouldn't work in OO just using larger fibre optics. I just carefully drilled a 0.5mm hole in the end of an LED to insert the fibre optic then ran it through from under the board to its location, once working I covered the LED and interface in black paint and PVA to seal it to minimise light loss. A number of people were very confused as to why one of my N gauge cars appeared to have working hazard lights and brakes on (flashing yellow LED and red LED respectively).

Heinz57 Posted May 19, 2013 Author Share Posted May 19, 2013 Thanks chaps. The express models flasher unit looks spot on for what I'm looking for. How easy is it to physicaly fit the LEDs into the cab? At Derby exhibition last weekend there was a trader selling just such flashing lights but I'm afraid I didn't take any more notice than that. If you can find the thread on the exhibition and see which traders were there, you may be able to find something useful. I remember seeing the guys with the model buses with the flashing units, and All Components Link to post Share on other sites More sharing options...
lankyphil Posted May 20, 2013 Share Posted May 20, 2013 What time period are you modelling? Most blokes now seem to use strobe type lights as a pose to the older rotating beacons... Link to post Share on other sites More sharing options...
stewartingram Posted May 20, 2013 Share Posted May 20, 2013 Pedant mode on: "Hazard" lights are actually the direction indicators, both left and right on together. But we all know you mean the ones on the roof - so pedant mode off. Stewart Link to post Share on other sites More sharing options...
