It's not about the automakers wanting to take old cars off the road. Chevyboy said none of the auto parts stores (which sell AFTERMARKET parts) has the bulbs either. The aftermarket has no vested interest in taking old cars off the road. In fact, just the opposite is true. The aftermarket WANTS old, out of warranty cars ON the road to sell more replacement parts for them. If the aftermarket doesn't offer a replacement bulb, then it must truly be not economically feasible to produce them.
