Flasher dim

[Voyager]

Could anyone please tell me why one of my rear indicators is flashing dimly ? Its the right speed and the front is ok - same thing happens when the hazards are on. I wonder if its a faulty or loose bulb ? cheers - my car is a w210 estate (2001)
thanks

Swap the bulbs over and check?
