When you're choosing automotive lighting, the right bulb depends on where it will go. The 2 Pack 9006 HB4 Fog Light Bulbs and the 10 Pack Philips 7440 CP Original Equipment Miniature Bulbs are two very different products: one is a two-piece LED fog light set, the other a ten-pack of turn-signal bulbs. Their listed prices are USD 37.95 and USD 13.86, so the price difference is significant.
Quick Verdict
If you need bright white fog lights, the 9006 HB4 set is the clear fit. If you need to replace turn-signal bulbs, the Philips 7440 10-pack is the practical choice.

Product Notes
2 Pack 9006 HB4 Fog Light Bulbs 6500K White Automotive Lighting Parts
This two-pack of 9006 HB4 LED bulbs produces a 6500K cool white light. The set includes an IP67 waterproof rating, a 30,000-hour operating life, and a 20000LM output, making it a strong candidate for fog lights or daytime running lights. The aluminum housing and chrome exterior finish are part of the design. It is listed at USD 37.95. The main limitation is the pack count: you only get two bulbs, so if you need to cover more than two light positions or a different bulb type, this set won't stretch. It fits vehicles that use the 9006/HB4 bulb size and is labeled as a universal fit.
NEW 10 PACK Phillips 7440 Cp Original Equipment Automotive Miniature Light Bulbs
This 10-pack of Philips 7440 miniature bulbs is designed for turn signal lights, with a W21W (7440) fitment code and a 3000K color temperature. The bulbs are made in Poland, and the set is listed at USD 13.86. The set comes with a 1-year manufacturer warranty. The main limitation is that these are not fog or driving lights; they are miniature turn-signal bulbs that produce a warmer 3000K light, not the 6500K white beam from the 9006 set. If you're looking for forward-facing illumination, this pack is not designed for that purpose. It is the better choice when you need a bulk supply of turn-signal bulbs at one time.
Final Choice by Use Case
Choose the 9006 HB4 2-pack for bright white fog lights and waterproofing. Choose the Philips 7440 10-pack for a batch of turn-signal bulbs with a 1-year warranty.
