Simple Diode Bridge for Pos Earth Simple Diode Bridge for Pos Earth
When upgrading older cars to LED lighting, some odd behaviour can occur. This is usually because car lighting was designed around filament bulbs and they are simple and fairly crude devices, and LED bulbs are sophisticated and sensitive electronic devices, and therefore a great deal fussier. One frequent problem when upgrading to LED flashers is that a single dash or switch display bulb is connected to both left and right indicators. To avoid joining them together, car makers reverse the polarity from the indication to one side and revert on the other. Electronics can't live with this so the result is either a dead short, or the LED protection circuits kick in and nothing works. The cure is easy and inexpensive (when you know how) in the form of a simple diode bridge. One of it's 3 legs becomes the new feed to the warning light input (usually found at the "P" terminal on the old flasher relay) The other two legs just connect to the left and right indicator lives anywhere betwee…

Diode Blocking Leads Diode Blocking Leads
Because car electrics generally use a common earth system and everything electrical is connected to everything else on the earth side, this can occasionally cause problems when the more sensitive LED lighting is installed, but the problems are easily solved, as long as you know how. Electricity can behave like water, and when a circuit is turned "off", it is termed low pressure and this circuit can provide a path to earth for any trickles of energy lingering around or escaping from "leaky" switches. It may not show up when all filament bulbs are fitted, but LED bulbs are far more sensitive and can show a glow when this happens. The answer is to use blocking diodes to shut the escape route, like fitting a one-way valve in a water pipe. If you fit high power stop/tail lights, you can cure feedback problems (if they arise), by fitting these leads into the tail light live feeds. They are suitable for either positive or negative earth systems and come with simple instructions and connectors…

Output Splitter Lead Pos Output Splitter Lead Pos
If you want to create a budget hazard warning light system on an early car, you can use an inexpensive two pin flasher relay and split the output by using one of these diode bridge leads. Use the black lead set on pos cars and the output will go to L & R indicators but will not cross over when the indicators are used. The price is for one diode split output lead with connectors and does not include P & P or VAT if applicable.…

Output Splitter Lead Neg Output Splitter Lead Neg
If you want to create a budget hazard warning light system on an early car, you can use an inexpensive two pin flasher relay and split the output by using one of these diode bridge leads. Use the red lead set on neg cars and the output will go to L & R indicators but will not cross over when the indicators are used. The price is for one diode split output lead with connectors and does not include P & P or VAT if applicable.…

Residual current drain kit Residual current drain kit
When fitting the latest electronics to old cars, there can sometimes be a conflict of technologies. When we know what is causing the problem, the cure is usually quite straightforward, but can be fiddly and time-consuming to apply in the confines of a car. One problem is that the sheer metal bulk of a car's wiring harness can store some electrical energy which remains and can cause chaos with electronics when a circuit is turned off. When this happens, the right sort of resistor can harmless drain the residual energy to earth. This little kit makes it easy because it comes with heatproof wires already attached and an earthing ring terminal at one end, with a snap connector and fixings supplied. What could take hours otherwise now takes minutes and tech support is available if needed. The price is for one kit and does not include P & P or VAT if applicable.…

Ignition warning light resistor kit Ignition warning light resistor kit
If you are thinking "Why do I need a resistor kit for my ignition warning light?" let me tell you. All car charging systems rely, to a greater or lesser degree, on the action of the bulb in the warning light to start the charging process. No bulb, no charging. If you upgrade to an efficient and bright LED bulb, then it has the same effect as no bulb, but worse than all of that is that if you leave the original bulb in place and it fails, so will your charging system. If the original bulb deteriorates, it will cause the charging system to work incorrectly. All of this can be simply and easily prevented by just ensuring that there is always the correct resistance available, regardless of what kind of bulb is fitted, or what condition it is in. This simple kit makes it quick and easy to do that. Just clip one end to the warning light live and the other to earth and the job is done. The prices is for one resistor lead with connectors and does not include P&P or VAT if applicable.…

Load Resistor Kit Load Resistor Kit
Load resistors can be highly useful in many instances when new electronic equipment get fitted to early cars. One case is where there is no equivalent electronic flasher relay to cope with LED flasher bulbs on a car. Adding these will "amplify" what the original relay "sees" and solve the problem. They can be difficult to fit in a car environment, but these ones have heatproof wiring already soldered on, a ring terminal to earth one end and fixings to enable you to just clip the other end to the live feed. The price is per kit of one resistor plus fixings and does not include P & P or VAT if applicable.…

Compatibility Kit for HP LED stop/tail Compatibility Kit for HP LED stop/tail
Many cars from the 1980's onwards have sophisticated bulb monitoring systems. They also have dull stop and tail lights. Upgrading to high power LED is the obvious solution but can lead to problems with bulb failure warning appearing (this is an MOT fail) and, on newer cars, fault codes being generated, which can only be cleared by a main dealer. The kit allows the fitting of high power LED stop and tail lights on all newer cars with no warning lights and no fault codes. It is available in the Classic Cars section complete with a pair of our very powerful red 380 stop and tail light bulbs but here the full kit is available without the bulbs to allow you to make your own choices.It is easy to fit and comes with full instructions and all connectors etc. The price is for the kit only and does not include bulbs, P & P or VAT if applicable.…

382 Compact silicon LED orange flasher bulb Fog 382 Compact silicon LED orange flasher bulb Fog
If you drive an older classic you will fully appreciate the need to have extremely visible indicators, BUT you may want them to be unobtrusive. These new high-tech silicon based LED bulbs are no bigger than the standard bulbs but are much brighter. They use new silicon technology to make them powerful but without any dotty effect. The material is also waterproof. Don't forget that you will need to use an electronic flasher relay (or resistors) to enjoy the use of LED flasher bulbs. The price is per bulb and does not include VAT if applicable or P & P. These ones are positive earth. See also the negative earth ones listed separately.…
