It was not my goal to try to shop for the best price for each type of bulb, but to use apples-to-apples in the sense that both bulbs being compared were from the same vendor (and were the same brand), so that even if the prices are not the best, they should both be similarly inflated. I compared dimmable LED bulbs, which are a bit more costly than non-dimmables, since the halogen bulbs are dimmable, and so a non-dimmable LED bulb would be an unfair comparison as it could not be used to replace a halogen bulb in all cases.

Bear in mind that the prices I quoted are in Canadian dollars, and so will appear higher than US prices due to the exchange rate. As I state above, the LEDs I chose to compare are dimmable ones, and so not necessarily the cheapest one can find. Don't get too hung up on the exact numbers; the salient point here is that LEDs cost at least a bit more than the CFL or incandescent bulb you replace, and so it takes a while before they save enough energy to recover the initial purchase cost. Only after that are the energy savings realised in a financial way. Clearly, using the LEDs saves *energy* that then becomes available for the EV to use, but how much *money* is saved will depend upon the type of bulb replaced, the particular LED bulb used to replace it, how the bulb is used, and how long the bulb lasts before needing to be replaced again. This just makes it difficult to communicate the advantage in a simple financial savings way, which is easier for most people to understand.
