👉 Flashers, often found in older vehicles, are a type of exhaust system component that can emit a distinct, pungent odor due to the presence of sulfur compounds and other volatile organic chemicals. These fumes typically arise from the oxidation of sulfur-containing materials, such as those used in fuel additives or brake pads, which can react with oxygen in the exhaust gases. The result is a smell often described as metallic, sulfuric, or even reminiscent of burnt rubber, making flashers a common source of unpleasant odors in garages and on the road. Proper maintenance and replacement of flashers can help mitigate these emissions and improve air quality.
