Final answer:
Bright Bulb needs to differentiate its LED bulbs or provide added value to consumers to gain a competitive advantage, beyond just pricing, cost-cutting, or aggressive marketing.
Step-by-step explanation:
For Bright Bulb to have a competitive advantage, it would require a strategy that differentiates its LED bulbs from competitors or offers additional value that customers recognize.
Given that the bulbs are considered very similar to those of competitors, a competitive advantage could be achieved through innovative features, superior customer service, efficiencies that allow for lower prices, or other factors that customers value and are willing to pay for. None of the options presented - higher pricing, sole focus on cost-cutting, identical features, or aggressive marketing - inherently provides a competitive advantage unless they result in perceived added value by customers.
