I have a wiring loom with connections for flashing indicators. Any advice on where to source the most appropriate lamp units would be appreciated. Currently I have single filament torpedo side lights on the front wings - I guess I could swap these out for side/indicator torpedos - which ones would be most appropriate?
At the rear someone has put two 1" holes in the body surrounding the boot opening (unless they are original and used for something?) so I could use them to attach a brackets and winkers or get some "D" shaped lamps that include flashers. Any recommendations of which to use and where to get them from?
Thanks. Colin.
1939 14 Flashing Indicators
Re: 1939 14 Flashing Indicators
Hello Colin,
From your description, the holes are original and used to adjust the boot pivots. Whilst any pre war vehicle is exempt from flashing indicators in the UK, bear in mind the regulations pertaining to later vehicles wrt position and visibility. Vehicles first used before 1 September 1965 may have direction indicators incorporated with stop lamps, or combined with side or rear lamps, in which case front indicators may be white and rear indicators red.
From The Road Vehicles Lighting Regulations
• Maximum distance from the side of the vehicle 400 mm
• Minimum separation distance between indicators on opposite sides of a vehicle 500 mm or, if the overall width of the vehicle is less than 1400 mm, 400 mm
• Minimum height above the ground: 350 mm
• Angles of visibility 80° outwards and 45° inwards
• Lens approval markings – not required
• Front indicator aligned to the front, rear indicator aligned to the rear:
An indicator fitted to a motor vehicle first used before 1st September 1965 and any trailer drawn thereby–
• if it shows only the front: White or amber
• if it shows only the rear: Red or amber
• if it shows both to the front and to the rear: Amber
• Wattage– Any front or rear indicator which emits a flashing light and does not bear an approval mark: 15 to 36 watts
• No vehicle shall be fitted with a total of more than one front indicator nor more than two rear indicators, on each side.
• Any number of side indicators may be fitted to the side (excluding the front and rear) of a vehicle.
When the flashing indicators first appeared in 1965, a conversion festoon bulb that flashed was marketed, the modern equivalent is once again available, so flashing semaphore arms are possible and legal.
As regards suppliers, a common approach is to fit amber motor scooter flashers front and rear, or many of the suppliers that you will find at an autojumble will supply the necessary bulbholders etc. You could also try making a supplementary bulbholder and use an amber, capless bulb commonly found in side repeaters in the sidelamp. With a bit of imagination, the D shaped rear lamps can be similarly fitted, and red/ clear lenses used.
Hope this helps
regards
Mike

Re: 1939 14 Flashing Indicators
On our 1939 16 I converted the rear D lamps reversing side by putting orange halogen bulbs in with a double filament small globe stop & tail in the red sides. The bulb holders for the stop and tail had to be changed. For the front I just put orange indicator bulbs in the existing wing top side lights and the side lights were fitted into the headlamps which means drilling them
You can get double conversion kits using miniature halogens (orange & white) from Holdens now though..
I kept the standard column switch and via double pole 3 relays the trafficators also operate.
Note these split D lamps are technically illegal in that the narrow red part has insufficient width area although I have never heard of anyone being stopped to have it measured! It passed all its MOT's till 1996 with its standard dip/pass head light set up too till I converted to double dip bulbs
I fitted a pendant reverse light below the number plate light.
Neat rear indicators can also be fitted using the reverse light with an orange bulb and suitable bracket. Modern high intensity LEDS are too large to fit D lamps and smaller diretional ones are invisible in some twilight/bright sunlight conditions
I was still happy with the brake light intensity so fitted a discrete LED high level strip light in the rear window - better safe than sorry as I had a number of close calls even with the standard single brake light set up
