What is the reason for half of the daytime running lights not working on the 9.5-generation Accord?

It is a malfunction of the LED lights. If the daytime running lights are broken within the warranty period, you can go to the 4S store for free repair. The following is a specific introduction about the Honda Accord: 1. Introduction: Accord (Accord), the practitioner of Honda's innovative spirit and global leading technology, has a global history of 38 years. The original tires of the Accord are Michelin ultra-high-performance sports tires. On April 16, 2018, the new generation of Honda Accord, that is, the tenth-generation Honda Accord, was officially launched in China. 2. Market positioning: The leading model of China's mid-to-high-end cars, setting a new technological benchmark in the mid-to-high-end car market.
As a long-time owner of a ninth-and-a-half-generation Accord, I once had the same issue where half of my daytime running lights stopped working. At first, I thought the entire assembly was broken and was really worried. Later, I saw similar cases on forums—it might be due to some LED modules burning out inside or oxidation causing poor contact in the plug. I just cleaned the connector with an alcohol swab, gave it a gentle wipe, and it worked fine, saving me a lot of money. The daytime running lights are designed with multiple small LEDs, so when half of them don’t light up, the common causes are dust buildup causing a short circuit or LED aging. I recommend cleaning the gaps around the light covers during regular car washes to avoid rainwater seeping in. If the issue persists, don’t force it open—take it to the 4S shop to check the wiring. Don’t overlook this detail, as it relates to driving safety.
I'm an auto mechanic who frequently deals with electronic issues in Japanese cars. For the 9.5th-generation Accord where half of the daytime running lights (DRLs) aren't working, the problem likely lies within the lighting system. DRLs typically use an LED array structure, so if one side fails, it's probably due to a circuit malfunction in one set of LED bulbs. This often stems from poor wiring contact or a partially blown fuse—for instance, oxidation at wiring terminals from frequent rainy-day driving can cause circuit breaks. Additionally, partial damage to the control module might disrupt signals, leaving one side unlit. Having handled many similar cases, I recommend using a multimeter to test circuit continuity. Avoid DIY fixes, especially if the car has aftermarket lighting modifications, as these can exacerbate issues. Prompt inspection at a specialized repair shop usually resolves it with minor repairs.
