Low Beam, High Beam & Turn Signal Solutions

The 2015–2017 Ford F-150 headlights rank among the most difficult to upgrade. First, the housings offer very limited space. Second, the factory light output leaves a lot to be desired.

Fortunately, the team at Headlight Revolution tested dozens of options to find solutions that actually work. Most importantly, every upgrade below installs plug-and-play, so you don’t need to splice wires or modify the truck.

Low Beam Upgrade

The F-150 low beam bulb sits high and offset inside the housing. Because of this placement, many large LED bulbs simply won’t fit.

After extensive testing, the team chose the GTR Lighting CSP Mini as the best solution.

Why It Works

• Nearly identical size to the OEM halogen bulb

• Fits the tight, offset housing

• Maintains proper beam alignment

• Delivers massive brightness gains

Additionally, the compact CSP chip design allows the bulb to sit correctly in the reflector. As a result, it preserves the factory beam pattern instead of scattering light.

Low Beam Test Results

• Stock: 230 Max Lux | OEM Beam Pattern

• CSP Mini: 1010 Max Lux | Identical OEM Beam Pattern

In other words, this upgrade increases usable brightness by more than four times while keeping proper beam control.

High Beam Upgrade

Unlike the low beam, the high beam bulb sits centered in the housing. Therefore, you can install a larger, more powerful LED option.

The clear winner was the GTR Lighting S.V-4 LED headlight bulb.

Why It Stands Out

• Fan-cooled design for consistent output

• Extremely high lux readings

• Maintains strong beam focus

• Reliable thermal management

Because the high beam housing allows more room, the S.V-4 can operate at full potential.

High Beam Test Results

• Stock: 660 Max Lux | OEM Beam Pattern

• S.V-4: 2710 Max Lux | Improved OEM Pattern

Consequently, this upgrade delivers over four times the intensity of the stock high beam.

Turn Signal Upgrade

Many owners forget the turn signals. However, they complete the look of a true LED front end.

The best choice here is the GTR Lighting Carbide Canbus 2.0 LED bulb.

Why This Bulb Matters

• No external resistors required

• Built-in CANBUS compatibility

• Eliminates hyper-flash

• Much brighter than stock

Previously, most LED turn signals required load resistors. Now, this updated CANBUS technology solves that issue internally. As a result, installation remains simple and clean.

Final Thoughts

Upgrading the 2015–2017 Ford F-150 headlights requires careful bulb selection due to space limits and factory wiring controls. However, when you choose the right components, the results are dramatic.

• Low Beam: GTR CSP Mini

• High Beam: GTR S.V-4

• Turn Signals: Carbide Canbus 2.0

Together, these upgrades transform nighttime visibility while maintaining proper beam control.
