You can still buy the "less expensive" incandescent bulbs that are actually much more expensive than LED's now (plus the risk of changing high lights on a ladder every 9 months.
Did you read the parent post? This is a case of buyers who want to buy electric... who walk in prepared to buy electric... and the sales people steer or even actively push the buyer away from electric. Mainly- again from the article- because the electric car will cost the buyer LESS money on maintenance.
You can bet the dealerships have set up commission structure to encourage sales of gasoline cars too.
Electric cars don't make as much sense as they did in 2014 with oil breaking $40 a barrel. But in 2-3 years oil is going to scream back up to over $100 (inflation adjusted) a barrel (it's done it twice before) and electric cars will be almost free to buy then when you consider improvements in battery life and capacity combined with an average $16,000 gasoline savings vs an average $1600 electricity cost. Plus another $4,000 in reduced maintenance costs.
The gas car is the "less expensive" bulb that breaks down and requires more maintenance AND burns 10x the energy that that the "more expensive" bubls do.
Most LED bulbs (now at $4.98) pay for themselves in 3 months now. The rest is free money from reduced energy bills.
