Smd Led Park Bulbs

I have done some research on smd led park bulbs.I see that most european cars uses can bus, which also then needs can bus park bulbs, and a non can bus car can use normal led park bulbs.I want to know is there any damage that can ocur to the vehicle if you put normal led parks into a can bus vehicle except for the warning light to come on on the dashboard.

Do it once,do it right - This means no short cuts. You never get paid twice for having to do the job twice because it wasn't done right the first time.

My understanding is the can bus LEDs merely include a resistor to imitate the load of normal bulbs thereby making current sensors think the bulbs are fine tho they usually won't sense if a LED has failed. Hence they can be used in any vehicle with lamp sensor alerts.
Of course that defeats the purpose of using LEDs for power saving reasons - ie, they'd be used for color or lighting reasons or by those that expect (but might not get) longer lamp life.

Using unballasted LEDs - as in no parallel resistance; not dc-dc converter ballasts etc - should not cause any damage other than irritation. I don't know of any modern system that immobilise vehicles because of light outages tho such designs would not surprise me....
However LED substitution may breach local vehicle regulations - especially if they defeat OEM sensing systems.


My preference is to modify the sensing circuitry to maintain its original functionality. That's what I do for flasher cans when substituting LED flashers but compatible modifiable flasher cans are easy to obtain; vehicle lamp sensing systems are more involved and vehicle specific.    

Thank you Old Spark!
