I don't think so. That bulb should have only one filement. I believe Joe W is on to the problem although the voltage thing is a little vague. The 'blink' rate or speed is determinded by the amount of current passing through the 'blinker' control and light circuits. The current in turn is controlled by the total resistance of the circuit. The voltage drop across the circuit remains the same. I thinks what might want to be said is...the right front blinker circuit has a higher resistance total than the left circuit due to bad contacts, corrosion, bad ground, etc. BTW, did you check to make sure both bulbs are the same type? If no numbers can be found, switch the bulbs. If the problem follows the bulb, you have it solved.
