Well the title just about explains what I want. I would like to know how exactly does the lighting system on new skodas work. I own a 2011 roomster, and I from what I've benn reading it's likely that it uses a light control unit that turns lights on and off depending on the commands it recieves from somewhere else, and this module also has a maximum load it can handle per output. In some occasions if you use led lights instead of filament bulbs, it may not work becasue it considers the load to be too small. Is this true? Is there any detailed information around?

Thank you very much for reading.

P.D. The reason I'm interested is because I do not want to burn the unit (if it exists) if I overload it with too many bulbs.

Maybe this is the wrong forum?

In the good ole days, one could just about wire anything up to the lights, but now I'm not too sure. Does anybody know anything about the lighting system on skodas?

It might be useful to know what you want to add in to the system.

Hi,

Need to know if you have standard headlights or cornering ones, standard is just basic wiring thro the light switch and dip/main beam relay,any extras need to take into account fuse loading and wiring size,

If you have cornering headligths fitted they are controlled by a electronic module,would need to know what load you are thinking of before I could advice.

Hi! Thanks for answering. Well, basically I would just like to inform myself how it works on my roomster. I just have the standard headlights, but I do have a feature that warns you if a bulb is burnt or not. I have a Kia too, and in that car you can't replace the bulbs for leds because it insists in warning that the bulb is out, when it really isn't.

My projects for the roomstar are still in the planning stage, until I get all the necesary information. But just so as you get an idea here are the basic ideas that are bouncing around in my head:

1- Installing parking sensors (they have to be connected to the rear lamps). Consumption is low, I doubt this will be a problem, but, of course, I don't know.

2- Making the other rear fog light work. I'm not sure if cabling it in parallel with the working one is a good idea as that implies doubling the load.

3- Adding a 12V connector plug in the boot.

4- Changing the boot light for something brighter as the factory one is really really poor.

5- Adding a light underneath the radio so as to see what's there during the night. At the moment, that area is totally dark at night, which makes looking for things more tricky while driving. This light I only want it to work when the headlights are on.

6- I might change the roof interior lights for leds, but this isn't exactly a priority at the moment.

Before I start doing these things, I am trying to gather as much info as possible. If anybody can help that's be great. I've read already read threads about similar projects to mine. I am mainly interested in how the lighting system box works which I suspect my new roomstar has. I am in no hurry in performing these mods as it is brand new and is still under guarantee.

Thanks very much.

Doesn't anybody know how the lighting system works? Or what the maximum safe load the rear foglight can stand? Would it stand two bulbs in parallel?

The Self Study Program for the VWUSA Jetta Mk 5 in the link below might be usefull for understanding how the Canbus system works.

Good stuff! Great introduction to what I may find in my roomsta! Thank you veeeeery much DGW.
