Fault light Bulbs

Postby D1705 » 06 Jun 2016 21:46

Hi all,

Does anybody know of a supplier for the fault lamp bulbs we have none left.
Bulbs are 6V 3W SBC base b15d, I know you can get motor cyle bulbs but these are single contact base not twin.

Regards

Believe these have not been made for some time, and remaining stocks now exhausted.

I suspect Pete has already tried but as a long shot you could ask Unipart: the cat number appears to be 054/035274.

Unfortunately the last bastion of these bulbs was the HST power car and as of 2008/9 the last old cab desks were replaced removing general day to day TOC requirements for them.

We modified 41001's indicators to LEDs from the word go - although they need a bit more work as are rather temperamental on occasions!

Gary
Did you use LED bulbs in the existing indicator or replaced the complete indicator unit?
Thanks in advance

Took the fault light unit apart and replaced the tufnol backpiece with a pcb that had the leds and circuitry mounted on it. Keeps the authenticity from the front - looks like a fault light, works like a fault like but modern stuff behind it.

Nigel - I think you have the wrong code for those bulbs. Assuming that the base has a single electrical contact, the last letter of the bulb code should be 'S' (for single); 'D' means double contact. Looking at some diagrams of standard bulb fittings, I also think the code as a whole for a single contact bulb with a 15mm base should be BA15S. This link shows illustrations and measurements:
https://www.google.co.uk/search?q=%22ba ... h6vOcS_JtM:

The good news is that 6V, 3W BA15S bulbs are still available from a specialist bike supplier, Paul Goff - priced at £1 each (min. order £5, plus £3.50 P & P). The P & P charge is a flat rate £3.50 for all orders up to a face value of £15, so if you can order up to 15 of them without increasing the P & P charge.

Contact details for Paul are as follows:

Post: Paul Goff, 62 Clare Road, Prestwood, Bucks. HP16 0NU

E-mail: norbsa02@aol.com

Phone: 01494 868 218 - 9.00am - 5.30pm, Mon./Fri.

Re. Paul's phone number - two points to note; he says (and I quote):

"Please leave a message if I'm out. Don't phone in the evenings, it makes me grumpy."

You have been warned!! 8)

By the by; I've no connection with Paul, other than as a very satisfied customer. He also sells quite a range of LED replacements for standard bulb types, and I can speak from experience about them. You can buy them cheaper on E-bay - but the cheapos start dying on you within a year or so, whereas his LED replacements last . . . and last . . . and last . . . your call!

Hi, the following companies supply and have in stock 6V 3W SBC base b15d bulbs. These do appear to be single middle contact bulbs rather than dual contact. However this is my assumption from looking at a picture side on.

Cp lighting 020 8391 7400 http://www.cp-lighting.co.uk

Lamp specs 020 8391 7411 this may be the same company

First Light 01737 845540

Hope this is of some help.

Glad to be able to log on again after being refused for 4 years or so.

No, Skeggy - if it's labelled BA15D it's got twin contacts on the base; but this bulb shown by CP Lighting is definitely a single base contact BA15:

http://www.cp-lighting.co.uk/18X35-6V-3W-500mA

It's good to know that there at least a few companies who can still supply them (rather than going through the routine of sucking in through their teeth and saying "Like hen's teeth, these days, guv - no call for 'em!"), and at a reasonable price, too! :)

With best regards,

Hi Jack,
If it's dual contact bulbs you want and they are not available could you not change the holder to single contact and fit bulbs that are about.

I don't think a single centre contact will work because the return is through the cap - both poles need to be 'floating'.

To be honest, Gordon, I'm a bit confused, now.

When I read the original post, I assumed that the OP was after bulbs with a single contact on the base (i.e., the BA15S), which are far less commonly seen than the twin contact bulbs, the Ba15D. The Ba15D type is the same size, shape and internal connections as the 12V, 5W type used in older cars as sidelights - but they are still widely available in 6V versions.

The single contact Ba15S types are far less common. I was given one by an S & T techie from a local steam railway (taken from a bit of signals equipment), and asked if I could find a supplier. When I took it into a local motor factor - old school, really knows his way about - he said he'd seen a few illustrations of them in old car handbooks, but he'd never seen one himself. When he checked through his suppliers' catalogues, Ba15S bulbs weren't listed anywhere.

But maybe I misunderstood the original post? With the sweltering hot, muggy weather we've been having over the last few days, my elderly brain has been struggling a bit - at times, it was as bad as being back in Malta with the RAF - thank Heavens it's cooled down a bit at last!!

Re. Sulzermeister's post; yes, it's not just a matter of changing the bulb holder - the wiring would need to be changed, too, as the metal bucket is completely insulated from the filament on the double contact bulbs, but is attached to one side of the filament on the single contact bulbs. These often rely on being clamped onto an earthed metal plate to complete the circuit.

With best regards,

Jack
