how to replace original brake light with LED?

I have already replaced the indicators, reverse lights, and all interiors, and want to complete the project by replacing the brake lights. As you might know the original bulb is dual filament and therefore, two different currents would go through the bulb. With LED pulling in so little power I've read that current would back-feed through the low-beam light and turns on other lights. I'm assuming I'd need to fit some diode in-line to prevent back-feeding power, but I'm unsure what diode to get nor the fitting of it.



Would appreciate if anyone has that knowledge can chime in. Thanks in advance.

Sylvania brand. Go for those. My car uses 7443 bulb number for the brake light, which is a dual filament bulb. 7440 is the single filament version of that bulb. Search “sylvania LED 7443” on Amazon and find a red colored one. Even though my car has a red tinted lens on the housing for the brake light, if you get a white color 7443 bulb, it may not look red on the streets especially at night with an LED being as bright as they are. Plug and play install, no extra wiring needed, works great, no issue. You might have luck finding that bulb at a car parts store though.

Quoting myself here. I have a US-spec LE trim model. I've had zero issues with LED brake lights for the last year. No resistors needed, no extra wiring, no other modifications, nothing. Just get reputable LED bulbs for the appropriate sockets and throw them in. No problems.

The brake light circuits are good for 5 amps (refer to the fuse panels to verify, I could be wrong) the LEDs are usually between 1.5 - 2.0 watts, which is no more than 0.2 amps at 12 volts... no resistors needed.

Turn signals, however, resistors are needed with LED bulbs otherwise you get hyperflash. That retrofit is easy though. 2/10 difficulty, easy DIY in 30 minutes or less. I've done full LED conversion on all my bulbs. Headlights, fog lights, signals, reverse, brake lights, miscellaneous marker lights, I've had no issues aside from shitty cheap bulbs flickering on me.

Good LEDs aren't cheap, especially headlights. Don't buy cheap Amazon/Ebay LEDs by brands that aren't big name, they don't last long.

I recommend Sylvania LEDs. You can find them at autoparts stores as well as Amazon, etc.

As for headlights, I recommend headlightrevolution.com (warning: NOT cheap at all, but they ARE worth it)
