Can anyone tell me which LED side lights are uk legal and will not show dashboard warning lights?

[Exdee]

Can't help you with the legal bit but you should not get any errors on the dash. The car does not have CANBUS.

Thanks for the information regarding the Cambus.

Does anyone know whether LED side lights would fail mot?

[PilgrimIS]

I'm pretty sure the LED sidelights are not road legal so would fail an mot, however I know a lot of folk with them fitted and not had any issues so I guess it's down to taking that decision.

[roc888]

Are there any halogen side light bulbs which are bright and similar to LEDs?

[roc888]

Has anyone used Philips blue vision ultra bulbs?

I fitted my LED side lights a few years ago and its passed all MOT tests including two done at a Lexus Dealership.

Hi Mike,

Can you tell me which LED side lights did you get? Can you provide the website link.

Thanks.

HI,

I got them in 2010 off eBay and they are still working fine, the link is no longer valid but they were described as - LEXUS IS220/250 2006 NO CANBUS ERROR SIDELIGHT LED BULB.

Looked like the ones shown below if any help.

Sorry about this but can you explain 'CANBUS' please.

Just out of curiosity, but it might be useful to me, who knows!

There is a good explanation here mate: http://www.car4play.com/forum/post/index.htm?t=9436

If the LED is not compatible with canbus your car will throw up faults. As far as I know the is220d doesn't use canbus, I've only put LEDs in my wing mirrors so far and they have caused no problems

I think CAN bus is the nervous system of the car (http://en.wikipedia.org/wiki/CAN_bus)%C2'>

IS250 will have a lot of CAN bus infrastructure, but may be using conventional method for turning lights on and off rather than using the bus.

I think Exdee mentioned above that the is250 does not have CAMBUS and therefore LED side lights are ok.

CANbus is an electronic signalling system used in modern cars. It's designed to permit more powerful communication with different parts of the car and to save wiring.

Take the headlights, for example. In a traditional car, your headlamp switch would operate a relay (an electrical controlled switch) which would turn on the high-power circuits to the headlights. Heavy duty cables would go from the relay to each headlight. A similar circuit would be repeated for the main beams, for the indicators, etc.

With CANbus, a single heavy cable goes from the Battery to each lamp cluster. A computer in your headlamp stalk senses the position of the switch, and that computer sends a signal over some thin CANbus cables to each individual lamp cluster. A computer in each individual lamp cluster controls the individual bulbs in the cluster. As there is a computer in each cluster, it is very easy for that computer to check the operation of each lamp and send back a signal to the dash computer telling it that the bulb is malfunctioning (the dash computer then responds by displaying warning lights and an error message).

The IS series use CANbus extensively between the various computers. The issue with changing bulbs is therefore nothing to do with CANbus, but whether the car is equipped with bulb malfunction detection.

BMW and Merc cars are equipped with bulb malfunction detection systems. Lexus cars are not.

The issue with LED bulbs is that they are extremely energy efficient. In cars with bulb malfunction detection systems, the sensors are not expecting such high efficiency and instead treat it as a malfunction, causing the dash to display a bulb malfunction message.

Thank you for the answers to the CANBUS question, very informative and helpful.
