DAYLIGHTER British Pre-Focus, H4s & Bayonet Cap

 

LED BRITISH PRE-FOCUS HEADLAMP BULBS

As fitted to British bikes late 1940s - 1970s

New High Power versions now in stock, see below

 

This is our new British Pre-Focus headlamp LED, these fit straight into your existing BPF headlight with no adapters, resistors or anything else required, now with new shorter heatsink & improved beam pattern from Sept. 2019

Previous BPF LEDs have had the power limited by a very simple heatsink, the Daylighter has a more sophisticated heatsink allowing much more powerful LEDs to be fitted.

The power consumption is under 8W so you can leave them running all the time you're riding and at night they will give a better light than a standard headlight bulb.

They're great for dynamo systems, used with a LED stop/tail they only use as much power as a pilot bulb

Dual Polarity, as supplied the standard Daylighters will run on 6V/12V as well as positive or negative earth systems so there's no chance of buying the wrong one.

Now also available as a 12V only high power version. Brighter than the standard version with the same improved beam pattern. These are also dual polarity.

 

The LEDs are positioned like the filaments in a standard bulb as shown here, this gives a good beam pattern, with main beam not 'up in the trees' like some other LED headlight bulbs.

The heatsink is now no longer than the std. bulbs glass

Perfect for total loss systems, (or if your dynamo fails) you will still get a good light until the battery is almost flat.

Special Offer on LED British Pre-Focus headlight bulbs NEGATIVE EARTH ONLY

Before developing our Daylighter BPF LEDs, we sold sevaral hundred of the LD BPFs below. The focussing isn't quite as good as the Daylighters but they're cheaper £18.95 You won't notice the difference if you don't ride at night

These LED headlight bulbs draw very little current, only 6W, so are great for cars like Austin 7s with a low dynamo output and older bikes with a low power dynamo.

The light from these LEDs is 'whiter' & brighter than a std. bulb. They are ideal for 6V dynamo systems, particularly with the older 'short' dynamo.

If you use your headlight mainly as a daytime riding light & only occasionally at night they are ideal.

These are great for daytime riding lights, you can leave them on all the time without worrying about your battery.

Suitable for 6V & 12V systems.

We have had some alterations made to these from the standard factory spec. to improve the beam pattern.

Perfect for total loss systems, (or if your dynamo fails) you will still get a good light until the battery is almost flat.

NEW 'DAYLIGHTER ' Bayonet Cap BA15d headlight bulb replacements

Our Daylighter LED headlight bulbs produce a much 'brighter, whiter' light and consume a lot less power than standard or Quartz Halogen bulbs. Ideal for the low power Dynamos fitted to Pre-War cars & Motorcycles.

They produce MUCH more light than a std. 6V or 12V std bulb, probably about the same as our 12V 40/45W Quartz Halogen versions while only drawing 7W or so, meaning they can be used all day as a daytime riding light without straining the dynamo.

NEW 'DAYLIGHTER 2s' H4 5K headlight bulb replacements

Our Daylighter LED headlight bulbs produce a much 'brighter, whiter' light and consume a lot less power than standard or Quartz Halogen bulbs.

LED headlamp bulbs must be fed from a battery supply, if your headlight doesn't light until the engine is started they are not suitable.

These are our new 5000 Lumen Daylighter H4 LEDs.

The original Daylighters (see below) are very bright at 4000LM, but this new version is even brighter.

The beam pattern is excellent , if anything better than before & they draw only 30 Watts.

The heatsink is positioned in front of the mounting rather than behind so not taking up so much room. No silly fans required.

These have to be seen to be believed, the light is exceptional & dips correctly so doesn't blind or dazzle oncoming traffic.

Specification:

Top quality Philips ZES LEDs

Operating Voltage 9V - 32V DC

Light output 5000 LM (a standard H4 is around 1500)

IP Rating IP65

Power consumption 30W

Colour temperature 6500K

Operating life > 30,000 hrs.

Operature - 40 - + 50 Deg. C.

Pt.no. H4LED5K Price £37.95

Suitable for 12V Negative or positive earth

 

They may look bulky, but the light from the LEDs passes unobstructed onto the reflector where it is directed forward as the beam.

The back of the bulb is 10MM longer than a std. bulb, but this has proved to be no problem in use.

They draw only 30 Watts so even a pre-war dynamo can run one of these & give 21st century lighting

On a total loss system (or if your dynamo packs up) you will still get a good light until the battery is almost dead because they will light as normal down to 9 Volts.

 

3 pin socket to suit Pt.no. HL13125 £2.95

Socket connections: Blue is earth, white dip & black main

If the body of the socket is grey, then Black is earth

It is not possible to fit the H4LED5K to Wipac Quadoptic H4s. The 3 moulding bumps shown here & the black shield foul the heatsink. Also cannot be fitted to Bosch & some types of Hinckley Triumphs H4s..

They will however fit any other type of H4 headlight.

The Daylighter H4 4K below are best here

If your car/bike has a 'Blown bulb warning light' this will probably be lit when any LEDs are fitted.

The H4LED5K comes with fitting instructions which also covers other versions not shown here & shows the power consumption as 55W. Ignore that, it is only Chinese optimism - they draw 30W.

 

DAYLIGHTER H4 4K
LED H4 headlight bulb replacements

The light is 'whiter' & brighter than a Std. H4 bulb, but more importantly, the beam pattern is correct.

As seen in the LH image, the LEDs are in the same position as the filaments on a std. H4. This ensures a good beam pattern & is often not the case. I have tested many H4 LEDs and most give a poor beam pattern. There are plenty of duds out there.

In Lucas & Wipac motorcycle headlights the dip beam is just the same & on main beam it is wider & brighter.

If we say that the light output of a normal H4 is 60/55W, then these are about 70/60, but they only draw 25W from your bikes power supply not 60W. Ideal for a dynamo bike converted to 12V.

They plug straight into the existing H4 socket and do not have a bulky 'driver' in the lead. The heatsink does not get too hot.

On a total loss system (or if your dynamo packs up) you will still get a good light until the battery is almost dead because they will light properlydown to 9 Volts.

       

With the socket, the overall length is almost the same as a std. H4 so fitting inside the headlight should be no problem.

I also stock a shallower Wipac H4 headlight which gives more room for bikes with a headlamp nacelle & speedo.

Unlike most headlight bulbs, when on Main beam both 'filaments' light together, giving a better overall coverage especially in poor visability
