Heater Control Bulbs

Our T3 / T4 / T5 Heater LED Car bulbs are available in Blue / White / Red / Green colour variations. They are used for a variety of car lighting modifications such as Dashboard lighting, Speedo lights, Cigarette lighter, but most commonly as heater control illumination. We supply these Heater control bulbs in the flat topped style where possible (T3 is only available as a domed bulb), the flat top gives a greater light spread.

To find out which bulb you require simply measure across the top of the glass bulb on your original and this will be the size of the bulb you need 3mm = T3 / 4mm = T4 and 5mm = T5

Don't risk buying cheaper, inferior LEDs you will only have to strip them out again in a few months to replace them.

Please Note:
LEDs have + / - contacts so it is worth testing the bulbs before reassembling any modified area, if any bulbs fail to work then turning them through 180 degrees should cure the problem.

Frequently Asked Questions:

I have received my order but some of the bulbs do not work, is there anything I can try to resolve this problem?

LED bulbs have to be fitted the correct way round as they have a positive / negative (+/-) and will only work if installed correctly, please turn the bulb through 180 degrees and refit it, it should now work. All bulbs are checked before dispatch so for a customer to get a bullb that does not work is very rare.


I have seen cheaper kits available for my car, what's going on?

We buy in the highest quality LEDs on the market today. Working in partnership with various car clubs we have recognised the need for quality over price. We know that when you pay a bit more for our LED kits, you will be getting LEDs that fit, work and look good, first time.


I want LEDs for a vehicle that isn't listed, can you help?

Yes, absolutely. If you have a car that we do not list, please contact us and we will work with you to find out exactly what bulbs are required for your vehicle.


Having received my order some of the bulbs seem to be wrong can you please help me?

Yes firstly if the bulbs look to be the wrong type please check this how to change a 286 LED bulb link as this is often the majority of reasons customers believe incorrect bulbs are in their order. If you still have problems please do not hesitate to contact us, we will do everything we can to help resolve the issue as quickly as possible.


I purchased a festoon bulb and it's slightly too short / long can I exchange it please?

Yes an exchange is not a problem, firstly though please check to see if the contacts in the bulb holder can be closed / opened slightly, this can often help hold the bulb securely and as taking the original bulb out can alter the contacts this may be all that is required. If not please contact us for an exchange.


I fitted all the LEDs and they look great, however when I start the engine one or more of the lights flicker slightly is this common?

This is not a common problem but does happen occassionally, all that is required is a slight adjustment to the bulbs (as detailed in the letter sent with all LED orders), depending on the bulb type you may need to adjust the metal tabs on either side of the bulb to create a solid but not overly tight contact with the circuit board, or if you installed 286 wedge bulbs the contacts within the base will need pushing together to allow a firm grip on the bulb. This is a procedure best carried out when the kit is installed, but if you are experiencing the problem it is definitely something that needs rectifying as quickly as possible, vibration and flickering is one of the quickest ways an LED will fail.
