They are designed to fit into various interior light fixtures in vehicles, including dome lights, map lights, and trunk lights. These bulbs utilize LED technology to produce a bright, energy-efficient light, available in colors such as white ice blue and purple. One of the standout features of these bulbs is their non-polarity design, allowing for easy installation without the worry of connecting them in a specific direction.

For what purpose do DE3175 bulbs serve and what problems can they solve?

The primary purpose of DE3175 festoon LED bulbs is to enhance the interior lighting of your vehicle. They can be used in several applications, including:

To install these bulbs, follow these simple steps:

Turn off your vehicle and remove any existing bulbs.
Insert the DE3175 festoon LED bulb into the socket, ensuring it fits snugly.
Turn on your vehicle to test the new lights. If they do not light up, simply remove and reinsert the bulb, as it can be installed in either direction.
