Fitting LED interior lights
I am thinking of fitting LED interior courtesy light bulbs in my 2004 Vauxhall Corsa C 1.8 SRI in place of the current halogen bulbs. I want to do the same with the boot light. Are Car LED Light Bulb W5W 5X SMD-5050 Canbus whites suitable for this? Would they be safe with the plastic cover? The bulbs in my car dim automatically when the door is shut or the alarm is activated. I am not sure if my car has a Can-bus system.
If your interior lights come on when you unlock the vehicle and before opening the door, then the interior light system is controlled via the intelligent power distribution module. As your light dims slowly when the door is closed or the vehicle locked, this suggests you do have the above system.
After checking the data on those bulbs, I do not think that they will be suitable for your Corsa. They will work when the door is opened, but you may experience problems with them remaining on in a dimmed state when they should be off. This may be rectifiable using a resistor wired into the system, but I cannot confirm this.
