Not all vehicles are required to be equipped with fog lights, but rear fog lights are mandatory by law, while front fog lights depend on the vehicle's configuration. Fog lights are primarily used in low-visibility conditions. Front fog lights employ yellow light to enhance penetration, while rear fog lights are red to alert following vehicles. Regulations explicitly require that fog lights must be activated when visibility falls below 200 meters, accompanied by speed and distance restrictions. For example, when visibility ranges between 100 and 200 meters, the speed should not exceed 60 km/h, and the following distance must be maintained at over 100 meters. Fog lights are typically installed in low positions beneath the bumper, with front fog lights symmetrically arranged on both sides, whereas rear fog lights are usually positioned on the left side or both sides of the vehicle's rear. Note that any modifications to fog lights must comply with national standards, and professional installation is recommended to ensure compliance. Proper use of fog lights can significantly enhance driving safety in rainy or foggy conditions, but they should be avoided during normal visibility to prevent distracting other drivers.

Range-extended electric vehicles (REVs) are a type of hybrid vehicle that combines pure electric drive with a fuel-powered generation system. Their core feature is that the on-board fuel engine charges the battery pack instead of directly driving the wheels, thereby extending the driving range. These vehicles are usually equipped with smaller-capacity power batteries (e.g., 30-50kWh) and can travel 150-250 kilometers in pure electric mode. When the battery is low, the fuel range extender starts automatically to generate electricity, increasing the combined driving range to over 600 kilometers, which effectively alleviates the range anxiety of pure electric vehicles. In the Malaysian market, range-extended technology is particularly suitable for suburban areas where charging infrastructure is still underdeveloped or for long-distance travel scenarios. For example, the models jointly developed by Proton and Geely adopt a similar design. Compared with plug-in hybrid electric vehicles (PHEVs), range-extended electric vehicles are always driven by electric motors, providing a smoother driving experience closer to that of pure electric vehicles. In contrast to battery electric vehicles (BEVs), their refueling method better aligns with the current dense network of fuel stations in the region. Currently, the Malaysian government offers incentives such as road tax and registration tax exemptions for such new energy vehicles, but it should be noted that some range-extended models may not qualify for full subsidies due to the presence of fuel-powered generation units. With the expansion of charging networks and technological advancements, range-extended electric vehicles may become a transitional solution that balances practicality and environmental requirements.

The Electric Vehicle Range Extender (EV Range Extender) is an auxiliary power system primarily used to extend the driving range of pure electric vehicles. Its core principle is to automatically start and charge the battery when the battery power is insufficient through a built-in small fuel generator or fuel cell, thereby preventing the vehicle from being stranded due to power depletion. Currently, common types of range extenders on the market include internal combustion engine (ICE) type and fuel cell type. The former is powered by gasoline or diesel generators, while the latter uses hydrogen fuel cell technology. Both can operate quietly and are compatible with the 48V to 72V voltage systems of electric vehicles. For example, portable, installation-free range extenders range in price from RM300 to RM2900, with power covering 3kW to 8kW, which can meet the range needs of two-wheeled, three-wheeled and even four-wheeled electric vehicles. Some products also feature intelligent frequency conversion and low-noise design. The popularity of range extenders is closely related to the government's promotion of electric vehicle policies and consumers' concerns about range anxiety. However, its technical difficulties lie in how to balance volume, weight and power generation efficiency, while complying with emission standards. In the future, as the cost of fuel cell technology decreases, the application of range extenders in the commercial vehicle field may further expand.

The core difference between EREV (Extended-Range Electric Vehicle) and EV (Battery Electric Vehicle) lies in their power architecture and energy replenishment logic. EREV incorporates a fuel-powered range extender on top of a pure electric system; the engine serves solely as a generator to charge the battery and does not directly drive the wheels. Thus, the vehicle is always powered by an electric motor, achieving a combined range of 800-1,200 kilometers, which makes it suitable for long-distance travel or users with limited charging access. However, the secondary energy conversion may result in increased fuel consumption during high-speed operation. EVs rely entirely on battery power, featuring a simpler structure with energy conversion efficiency exceeding 90%, zero emissions, and lower maintenance costs. However, their range is constrained by battery capacity (typically 500-700 kilometers), depends on charging infrastructure, and exhibits more pronounced range reduction in low-temperature conditions. Regarding purchase cost, EREVs are generally over 10% more expensive than comparable EVs due to the additional engine system, though EVs may qualify for higher subsidies. For daily commuting with convenient charging access, EVs are more economical and eco-friendly. For frequent long-distance travel or range-anxious users, EREVs offer greater flexibility through refueling. Both technologies have distinct application scenarios, and the choice should be based on individual travel patterns, charging availability, and budget considerations.

Extended-Range Electric Vehicles (EREVs) combine the dual advantages of pure electric drive and fuel-powered generation. Their core feature lies in using the internal combustion engine as a generator to continuously supply power to the battery pack rather than directly driving the vehicle, thereby retaining the smooth and quiet driving experience of electric vehicles while significantly alleviating range anxiety. Taking a certain EREV model equipped with a 1.5-liter fuel engine as an example: its 39.05 kWh lithium iron phosphate battery delivers a pure electric range of 225 kilometers, and when combined with the fuel range-extender system, the total range extends to 1,065 kilometers—far surpassing most pure electric models. In terms of charging efficiency, EREVs require only 15 minutes to fast-charge from 30% to 80%, making them ideal for long-distance travel or areas with limited charging infrastructure. Moreover, EREV technology holds particular suitability for the Malaysian market. On one hand, the government has extended electric vehicle tariff exemptions until 2025 and is advancing charging infrastructure development (with a target of 10,000 charging stations by 2030), reducing adoption barriers. On the other hand, local consumers exhibit strong demand for SUVs and hybrid models (hybrid and pure electric vehicle sales are projected to grow by 52% in 2025). EREVs not only fulfill family users' dual requirements for space and range but also circumvent the limitations of pure electric vehicles during the current phase of underdeveloped charging networks. From an industrial standpoint, Malaysia is accelerating its electrification transition. Domestic brands like Perodua have already introduced electric models, while the entry of Chinese automakers' EREV technology will further diversify market options, creating a differentiated competitive landscape alongside traditional fuel vehicles and pure electric cars.
