How does this bulb match my GMC Acadia’s original specification?

The 13582912 is manufactured to match the form, fit and basic electrical characteristics of the OE bulbs used in Acadia rear lighting circuits. It is listed specifically as a replacement for OEM 19433735 and 13582912, so socket compatibility and mounting location match factory parts. Using a direct-fit replacement avoids adapters or rewiring.

• Designed to fit GMC Acadia 2013–2016 and 2017 Acadia Limited rear brake/taillight sockets
• Meets the same physical dimensions and connector style as OEM parts
• Plug-and-play installation—no special tools or wiring changes

Will the light be visible in daylight and at night?

This bulb is engineered for sufficient luminous intensity so signals remain noticeable in varied lighting conditions. During daytime driving the brake/taillight output is strong enough to be seen against bright backgrounds, and at night it provides clear, consistent illumination so following drivers can respond promptly. It’s not a high-intensity performance lamp, but it restores standard factory visibility.

• Brightness tuned for everyday driving visibility
• Consistent light output for both brake and taillight functions
• Improves signal recognition compared with aged or dim factory bulbs

Is installation difficult and what tools are required?

Installation is intentionally simple: the bulb is a plug-and-play replacement that fits the stock socket without modifications. In most Acadia rear lamp assemblies you can access the bulb through the trunk or tailgate area; remove the lamp access cover, twist out the old bulb socket, pull the old bulb, and install the Lochnchn unit. Typical installations take only a few minutes.

• No splicing or adapters needed—direct OEM-style connector
• Basic hand tools may be required to open the lamp access panel
• Follow vehicle manual lamp-access steps for a safe swap

What materials and durability features does this bulb include?

The Lochnchn replacement is constructed from ABS plastic combined with aluminum components for thermal stability and resistance to road vibration. Those materials help the bulb withstand normal operating conditions, including temperature changes and mechanical stress from regular driving. While not lifetime-guaranteed, the build targets long-term, trouble-free service as a cost-effective OE replacement.

• ABS plastic body for impact resistance
• Aluminum elements for heat dissipation
• Quality control targeted to match factory replacement expectations
